Question

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

Explanation:

Step1: Recall area - triangle formula

The area of a triangle is given by the formula $A=\frac{1}{2}bh$, where $b$ is the base of the triangle and $h$ is the height (the perpendicular distance from the base to the opposite vertex).

Answer:

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