Question

A triangle with an area of $150c{m}^2$ has a base length of $50cm$. What is its height?

• A. $3cm$
• B. $6cm$
• C. $9cm$
• D. $12cm$

Answer 1

The correct option is B $6cm$

Given:
Base of the triangle, $b=50cm$
Area of the triangle, $A=150c{m}^2$

Let the height of the triangle be $h$.
Using the formula for area of triangle,
$A=\frac{1}{2}bh$
$h=\frac{2A}{b}$
$h=\frac{2\times 150}{50}$
$h=6cm$
