Question

Find the area of the triangle below. Be sure to include the correct unit in your answer.

Answer 1

When given the base of and height of a triangle, you can use this formula:

$area = \frac{1}{2} bh$

Plug in the known values:

$area = \frac{1}{2} (18)(6)$

Solve:

$area = \frac{1}{2} \times 108$

$area = 54$

Add units:

$area = 54cm^{2}$
