Question

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

Explanation:

Step1: Recall the formula for the area of a triangle

The area of a triangle is calculated by taking half of the product of its base \(b\) and height \(h\).
$$A=\frac{1}{2}bh$$

Step2: Analyze each option

• Option \(A = bh\) is the formula for the area of a parallelogram.
• Option \(A=\frac{1}{2}bh\) is the correct formula for the area of a triangle.
• Option \(A = (\frac{b_1 + b_2}{2})h\) is the formula for the area of a trapezoid.
• Option \(A = 2bh\) is an incorrect formula for a triangle.

Answer:

\(A=\frac{1}{2}bh\) (the second option)
