Question

use formulas to find the area of the figure
oa 18 m²
ob. 14 m²
oc. 40 m²
od. 36 m²

Explanation:

Step1: Recall triangle area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

From the figure, the base $b = 9$ m and the height $h=4$ m.

Step3: Calculate the area

$A=\frac{1}{2}\times9\times4=\frac{36}{2}=18$ m²

Answer:

A. $18$ m²
