Question
The length of a rectangular garden is 16 metres and its
breadth is 8 metres. Find the length of the diagonal of a square garden having the same area as that of the rectangular garden:Solution
Using formula, Area = lb & Area = a2 = (Diagonal2)/2 Area of the rectangular garden = 16 × 8 = 128 m2 = Area of the square garden Therefore, Side of the square garden = √128 m2 Therefore, diagonal of the square garden = √2 x side ⇒ √2 x √128 = √256 ⇒ 16 m
