Question

what is the formula for finding the area of a triangle?
a = 2bh
a = bh
a = (b₁ + b₂ / 2)h
a = 1/2 bh

Explanation:

The area of a triangle is calculated by multiplying the base \(b\) and the height \(h\) and then taking half of that product. This is because a triangle is half of a parallelogram (which has area \(bh\)). The formula \(A = \frac{1}{2}bh\) directly reflects this relationship.

Answer:

\(A = \frac{1}{2}bh\) (the fourth option in the given list).
