Question

jazlyn wants to purchase a triangular trampoline. what is the formula for finding the area of a triangle? $a = \left(\frac{b_1 + b_2}{2}\
ight)h$ $a = 2bh$ $a = bh$ $a = \frac{1}{2}bh$

Explanation:

Step1: Recall area formula

The area formula for a triangle is derived from the relationship between a triangle and a parallelogram. A triangle is half of a parallelogram with the same base and height.
The area of a parallelogram is $A = bh$, so for a triangle it is $A=\frac{1}{2}bh$.

Answer:

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