3 days ago · In such a triangle, the legs are equal in length (as a hypotenuse always must be the longest of the right triangle sides): a=b a = b. One leg is a base, and the other is the height – there is a right angle between them. So the area of an isosceles right triangle is: \text {area}=\frac {a^2} {2} area = 2a2.

This means the area of each right triangle is exactly half the area of the rectangle. The general formula to find the area of any triangle is: \text { Area of a triangle } = \cfrac {\text { base } \times \text { height }} {2} Area of a triangle = 2 base × height. This can also be written as the following formula: A=\cfrac {1} {2} \, b h A = 21 bh.
