Question

What is the area of this triangle?

Answer 1

Answer: $54cm^{2}$

The area of a triangle is given by:

$A_{triangle}=\frac{(b)(h)}{2}$

Where:

$b=9cm$ is the base of this right triangle

$h=12cm$ is the height of the triangle

Substituting the known values:

$A_{triangle}=\frac{(9cm)(12cm)}{2}$

Finally, the area of this triangle is:

$A_{triangle}=54cm^{2}$
