Question

If perimeter of a rectangle is 14 cm and length is 5 cm, then find the area of the rectangle.

• A. 10 $c{m}^2$
• B. 8 $c{m}^2$
• C. 20 $c{m}^2$
• D. 15 $c{m}^2$

Answer 1

The correct option is A 10 $c{m}^2$

Given,
Length of the rectangle = 5 cm
Perimeter = 14 cm

We know that,
Perimeter of rectangle = 2(length + breadth)
14 = 2(5 + breadth)
7 = (5 + breadth)
So, breadth = 2 cm

Area of rectangle = length$\times$breadth
= 5$\times$2
= 10 $c{m}^2$

Therefore, area of the rectangle is $10c{m}^2$.
