Question

what is the formula for finding the area of a triangle?
$a = \frac{1}{2}bh$
$a = bh$
$a = (\frac{b_1 + b_2}{2})h$
$a = 2bh$

Explanation:

Step1: Recall area formula

The area formula for a triangle is half of the product of base and height.

Step2: Match with options

The correct formula is $A=\frac{1}{2}bh$.

Answer:

A. $A = \frac{1}{2}bh$
