2. The length of a rectangle is 5 cm more than its width. If the perimeter of the rectangle is 40 cm, find the area of the rectangle.

93.75 cm^2

Step-by-step explanation:

The breadth = x cm

length=x+5 cm

perimeter =2 (l+b) which becomes

2 (x+5+x)=4x+10 cm:

4x+10=40

4x=30

x=30/4=7.5

so, breadth = 7.5 cm

length = 12.5 cm,

area = 12.5*7.5 = 93.75
