Question
The length of a rectangular garden is 18 metres and its
breadth is 9 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 = 18 × 9 = 162 m2 = Area of the square garden Therefore, Side of the square garden = √162 m2 Therefore, diagonal of the square garden = √2 x side ⇒ √2 x √162 = √324 ⇒ 18 m
