Question

Find the altitude of the triangle whose area is 50 $c{m}^2$ and the corresponding base is 20 cm---

• A. $3cm$
• B. $4cm$
• C. $5cm$
• D. None

Answer 1

The correct option is C $5cm$

Let the altitude of the triangle be h cm.
We know that
Area of the triangle = $\frac{1}{2}$ base $\times$ altitude
or 50 = $\frac{1}{2}\times 20\times h$
or h = $\frac{50\times 2}{20}=5cm$
Hence, the altitude of the triangle is $5$ cm.
