Question

The area of a parallelogram shaped wall is $9.5{\text{m}}^2$. If the height of the wall is $5\text{m}$, find length of the base of the parallelogram-shaped wall?

• A. $1.9\text{m}$
• B. $2\text{m}$
• C. $2.1\text{m}$
• D. $2.2\text{m}$

Answer 1

The correct option is A $1.9\text{m}$

Let's draw a parallelogram ABCD of height $5\text{m}$
Lets assume base to be $x\text{m}$
Given,
Height of parallelogram $=5\text{m}$
Area of parallelogram $=9.5{\text{m}}^2$

As we know,
Area of parallelogram = Base $\times$ Height
$9.5=x\times 5$
$x=\frac{9.5}{5}=1.9\text{m}$.

Hence, length of the base of the parallelogram-shaped wall is $1.9\text{m}$.
Option (a) is correct.
