Question
The length of a rectangular garden is 9 metres and its
breadth is 2 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 = 9 × 2 = 18 m2 = Area of the square garden Therefore, Side of the square garden = √18 m2 Therefore, diagonal of the square garden = √2 x side ⇒ √2 x √18 = √36 ⇒ 6 m
