Question

If the area of a parallelogram is $144{\mathrm{cm}}^2$ and its base is $9cm$. then its height is

• A. $8cm$
• B. $12cm$
• C. $24cm$
• D. $16cm$

Answer 1

Answer: (D)

$16cm$

Area of parallelogram $=$ base$\times$ height

Given : base $=9cm,$

area $=144c{m}^2$

Let height be $h$

$\Rightarrow$ $144{cm}^2=9cm\times h$

$\Rightarrow$ $h$$=\frac{144{cm}^2}{9cm}$

$\therefore$ $h=16cm$
