Question

The perimeter of a rectangle is 120 m and its length is 36 m. The ratio of the width of the rectangle to its length is​

Answer 1

$b:l = 2:3$

Step-by-step explanation:

Given,

perimeter of a rectangle is 120m

it's length , l = 36m

To find The ratio of the width of the rectangle to its length.

Now,

Perimeter of rectangle = 2(l + b)

120 = 2(36 + b)

$\frac{120}{2} = (36 + b)$

$60 = 36 + b$

$b = 60 - 36 = 24m$

Now,

$b:l = 24:36$

$b:l = 2:3$
