Answer:
Width, b = 2.14 cm
Step-by-step 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.
