Rectangleperimeter formula: P=2(a+b)P = 2(a + b)P=2(a+b). Triangleperimeter formulas: P=a+b+cP = a + b + cP=a+b+c; or P=a+b+a2+b2−2ab×cos(γ))P = a + b + \sqrt{a^2 + b^2 - 2ab \times … WebEach side measures 7cm and you can calculate the length of its outline in the following way. Perimeter = 7cm + 7cm + 7cm = 21cm. Or, there is an easier way. Since the three sides are the same, you can multiply one side by 3 and the result does not change. Perimeter = 3 x 7cm = 21cm. And this helps you with an equilateral triangle.
