Question

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

• A. 7 $c{m}^2$
• B. 10 $c{m}^2$
• C. 20 $c{m}^2$
• D. 45 $c{m}^2$

Answer 1

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

Perimeter of rectangle
= 2(length + breadth)
According to given condition
14 = 2(5 + breadth)
7 = (5 + breadth)
breadth = 2 cm
Area of rectangle = length$\times$breadth = 5$\times$2 = 10 $c{m}^2$.
