Question

The length of a rectangle is 5.6 cm. The perimeter of the rectangle is 20 cm. What is the area of the rectangle?

Answer 1

Area of rectangle is `24.64` sq.cm.

Explanation:

Let width of rectangle be `w` and length , `l=5.6`

Perimeter of rectangle is `P=2(l+w)=20` or

`2(5.6+w)=20 or 5.6 +w =10:. w= 10-5.6` or

`w=4.4` cm. Area of rectangle is `A=l*w`

`:.A=l*w= 5.6*4.4=24.64` sq.cm.

Area of rectangle is `24.64` sq.cm. [Ans]
