Perimeter is the measure of length covered by the boundary of the shape. So, the units of the perimeter will be the same as the units of length. We can say that perimeter is one-dimensional. Hence, it can be measured in meters, kilometers, centimeters, and so on.
Apr 8, 2024 · Rectangle perimeter formula: P = 2 ( a + b) P = 2 (a + b) P = 2(a +b). Triangle perimeter formulas: P = a + b + c. P = a + b + c P = a+ b+ c; or. P = a + b + a 2 + b 2 − 2 a b × cos ( γ) P = a + b + \sqrt {a^2 + b^2 - 2ab \times \cos (\gamma)} P = a+ b+ a2 +b2 −2ab×cos(γ) .
