Question

what is the correct formula for the area a of a triangle with base b and height h?
a = (1/2)bh
a = bh
a = b^2h
a = 2(b + h)

Explanation:

Step1: Recall the area formula of a parallelogram

The area formula of a parallelogram is \(A = bh\) (base times height).

Step2: Relate the triangle to the parallelogram

A triangle with the same base \(b\) and height \(h\) as a parallelogram is exactly half of the parallelogram. So the area of the triangle is half of the area of the parallelogram.

Answer:

A. \(A=(1/2)bh\)
