Question

Find the base of parallelogram if its area is $80{cm}^2$ and altitude is $10$ cm.

• A. $6$ cm
• B. $8$ cm
• C. $10$ cm
• D. None of the above

Answer 1

The correct option is B $8$ cm

Given, area of parallelogram $=80c{m}^2$

Altitude, $a=10cm$

Let, the base be $b$

For a parallelogram,

$Area=Base\times Altitude$

$\Rightarrow 80=b\times 10$

$\Rightarrow b=\frac{80}{10}$

$\Rightarrow b=8$

Hence, the base of the parallelogram is $8cm$
