Question

the length and breadth of a rectangle are in the ratio 5:3if the perimeter of the rectangle is 64cm then the area of the square on the diagonal of the rectangle​

Answer 1

Here, Length will be 5x and Breadth will be 3x

Perimeter of a rectangle = 2 [L+B]

Here, Perimeter is given as 64 cm

So, 2 [5x + 3x] = 64

2 [8x] = 64

16x = 64

x = 64/16

x = 4

Length = 5×4 = 20 cm

Breadth = 3×4 = 12 cm
