Question

The area of a parallelogram is $60{cm}^2$and one of its altitudes is $5cm$. The length of its corresponding side is-

• A. $12cm$
• B. $6cm$
• C. $4cm$
• D. $2cm$

Answer 1

The correct option is A

$12cm$

A parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. The area of the parallelogram depends on the base which is one of its parallel sides and height. The perimeter of a parallelogram depends on the length of its four sides.

Given

Area of parallelogram $=60{cm}^2$

Length of its altitude $=5cm$

The area of a parallelogram $=$ base $\times$ altitude

$\begin{array}{rcl}& \Rightarrow & 60=base\times 5\\ & \Rightarrow & base=\left(\frac{60}{5}\right)cm\\ & \Rightarrow & base=12cm\end{array}$

Therefore the length of one of its corresponding sides is $12cm$

Hence, option A is correct
