what would be the length of the diagonal of a square plot whose area is equal to the area of a rectangular plot of 45 m length and 40 m width ?
a 2 = 45 × 40 = 1800 ∴ a = √ 1800 = 30 √ 2 ∴ diagonal of the square = √ 2 a = √ 2 × 30 √ 2 = 30 × 2 = 60 m answer b
diagonal(square_edge_by_area(rectangle_area(45, 40)), square_edge_by_area(rectangle_area(45, 40)))
