Question

The area of a rhombus is 72 $c{m}^2$ and its perimeter is 32 cm, altitude is---

• A. $8cm$
• B. $9cm$
• C. $4cm$
• D. None of these

Answer 1

Answer: (B)

$9cm$

We know that,
Perimeter of rhombus = 4 $\times$ side = 32 cm
or side = $\frac{32}{4}=8cm$
Now, Area of rhombus = side $\times$ altitude
or Altitude = $\frac{Area}{Side}$
= $\frac{72}{8}cm$ = $9$ cm
Hence, the altitude of the rhombus is $9$ cm.
