Question

he area of a rectangle is 22.5 cm the length is 10.5 the width of the rectangle is ( x+.6)cm what is the width

Answer 1

Width, b = 2.14 cm

Explanation:

Given that,

The area of the rectangle = 22.5 cm

Length, l = 10.5

Width, b = (x+0.6)cm

We need to find the width of the rectangle. The area of a rectangle is given by :

A = lb

So,

22.5 = 10.5(x+0.6)

22.5 =10.5x+6.3

22.5-6.3 = 10.5 x

16.2 = 10.5x

x = 16.2/10.5

x = 1.54 cm

Width, b = (1.54+0.6)cm

= 2.14 cm

So, the width of the rectangle is 2.14 cm.
