- Find the perimeter of the rectangle. The rectangle above has a length of 16 km and a width of 11 km. Even though we are not given the measurements of all four sides, we know that the other two sides also measure 16 km and 11 km, respectively.
- How long is the rectangle below if its perimeter is 154 ft and its width measures 25 ft? Sometimes, you’ll be presented with a problem wherein one of the dimensions is missing.
- If the length and width of the rectangle below are both decreased by 4 inches, find the perimeter of the new rectangle. In this example, we are asked to decrease the measurements of our original rectangle by 4 inches then using these new dimensions, we will find the perimeter of the new rectangle.
- The length of a rectangle is twice its width. What is the perimeter of the rectangle with a width of 6.8 centimeters? Before going into any calculations, let’s first identify and interpret the pieces of information given to us in the problem.
The perimeter of a rectangle is the total distance around the outside of the rectangle. For example, Perimeter is measured in units. Each side of the square is one unit. The perimeter of the rectangle is found by counting the units on each side of the rectangle.

The perimeter of a rectangle is the sum total length of all of its sides.
A rectangle is defined as a quadrilateral, or a geometric shape with four sides. In a rectangle, both sets of opposite sides are congruent, meaning that they are the same length.
Write down the basic formula for finding the perimeter of a rectangle.
This formula will help guide you as you calculate the perimeter of your own rectangle. The basic formula is:
P = 2 * (l + w)
Perimeter is always the total distance around the outside edge of any shape, whether it is simple or compound.
refers to the length of the rectangle, and
refers to the width of the rectangle.
Write down the formula for area and the formula for the perimeter of a rectangle.
Even though you already know the area of the rectangle in this problem, you will still need to use the area formula to find missing information.
The area of a rectangle is a measurement of the two-dimensional space within the rectangle, or the number of square units within the rectangle.
The formula used to find the area of a rectangle is
A = l * w
The formula used to find the perimeter of a rectangle is
Write down the basic formula for perimeter.
Perimeter is the sum total of all outer sides of any given shape, including irregular and compound shapes.
A standard rectangle has four sides. The two sides composing the length are equal to each other, and the two sides composing the width are equal to each other. Therefore, the perimeter is the sum of those four sides.
A compound rectangle has at least six sides. Think of a capital “L” or “T” shape. The top “branch” can be separated into one rectangle and the bottom “bar” can be separated into another. The perimeter of this shape, however, does not rely on breaking up the compound rectangle into two separate rectangles. Instead, the perimeter is simply:
P = s1 + s2 + s3 + s4 + s5 + s6
Each “s” represents a different side of your compound rectangle.
Organize the information you do have.
You can still find the perimeter of a compound rectangle as long as you have at least one full length or full width and at least three of the minor width or length measurements.
For an “L”-shaped compound rectangle, use the formula
P = L + W + l1 + l2 + w1 + w2
stands for “perimeter.” The uppercase
stand for the full lengths and widths of the entire compound shape. The lowercase

How do I compute the missing side of a triangle?
When dealing with a rectangle, you can find the length of the missing side by utilizing division or by manipulating the equation through your understanding of literal equations. In the context of triangles, a similar principle applies. If you know the area and the lengths of two sides of a triangle, you can employ appropriate formulas, such as the formula for the area of a triangle. To solve for the length of the missing side, the Pythagorean theorem is commonly used for right-angled triangles, and trigonometric ratios can be employed for various types of triangles. It ultimately depends on the specifics of the triangle in question.

Oct 1, 2019 · The area of a rectangle is (length x height). If we have a fixed perimeter of 100, and the perimeter is 2· (length + height), then (length + height) =50. If we call one side x, the two sides can be represented as x and (50-x). The area of any rectangle we make form this rope is then A=x· (50-x), or A=50x-x 2.
