Question

the side of a rectangle are in the ratio 2:3and the perimeter is 20 cm find the side of rectangle​

Answer 1

Step-by-step explanation:

In rectangle ABCD,

Given,

perimeter of a rectangle = 20cm

Ratio = 2:3

So, let us consider the side as ‘x’

Length of rectangle (l) = 3x

Breadth of the rectangle (b) = 2x

We know that,

Perimeter of the rectangle = 2(L+B)

20 = 2(3x + 2x)

10x = 20

x = 20/10 = 2

Length of the rectangle = 3×2 = 6cm

Breadth of the rectangle = 2×2 = 4cm .
