Question

Find the area of the triangle whose one side is 80 cm and the corresponding altitude is 25 cm---

• A. $1000c{m}^2$
• B. $10,000$ $c{m}^2$
• C. $100$ $c{m}^2$
• D. None of these

Answer 1

Answer: (A)

$1000c{m}^2$

We know that
Area of the triangle = $\frac{1}{2}$ side $\times$ corresponding altitude
= $\frac{1}{2}\times 80\times 25c{m}^2$
= $1000c{m}^2$
