16 Ιαν 2024 · If you are calculating the perimeter of a rectangle in real life, use a ruler, yardstick, or tape measure to find the length and width of the area that you are trying to measure. If you’re measuring outdoors, measure all sides to see if the opposites are truly congruent.
Here are the perimeter formulas for the twelve geometric shapes in this calculator: Square perimeter formula: P = 4a P = 4a. Rectangle perimeter formula: P = 2 (a + b) P = 2(a+b). Triangle perimeter formulas: P = a + b + c P = a+b+ c; or. P = a + b + \sqrt {a^2 + b^2 - 2ab \times \cos (\gamma)} P = a+b+ a2 +b2 − 2ab×cos(γ) . ; or.
