Question

1.
The ratio between the length and breadth of a rectangle is 5:3. If the area of the rectangle is
135 cm", find the perimeter of the rectangle.
(a) 32 cm
(b) 48 cm
(c) 24 cm
(d) 36 cm​

Answer 1

let the length and breadth ratio is 5x and 3x.

then perimeter is equal to sum of all sides.

2(l+b)

2(5x+3x) = 135

2(8x) = 135

16x= 135

x = 135÷16

x then put value of x in 5x and 3x
