The diagonal of a square is 15 m; find the length of its one side and perimeter.

Question

KnowledgeBoat · Accepted Answer

Given: Diagonal of the square is 15 m. Let each side of the square be `a` m. Then, by using Pythagoras theorem, ⇒ Diagonal² = Side² \+ Side² ⇒ (15)² = a² \+ a² ⇒ 225 = 2a² ⇒ a² = ⇒ a² = 112.5 ⇒ a = ⇒ a = 10.6 As we know that perimeter of the square = 4 x side = 4 x 10.6 m = 42.4 m Hence, the side of square is 10.6 m and its perimeter is 42.4 m.
