A triangle has a base of $14$ inches and a height of $9$ inches. What is the area, in square inches, of the triangle?

$63$

$126$

$23$

$31.5$

Show answer and explanation

Answer: A

The area of a triangle is $\frac{1}{2} \times \text{base} \times \text{height}$ . So $A = \frac{1}{2}(14)(9) = 63$ square inches.

Choice B forgets the factor of $\frac{1}{2}$ and gives the area of a rectangle with the same base and height.
