Question

What is the area of a triangle that has a base of 15 1/4 in. and a height of 18 in.?

Answer 1

$\frac{1}{2}$×base×hight
$\frac{1}{2}$×15$\frac{1}{4}$×18
$\frac{1}{2}$×$\frac{61}{4}$×18
137.25 in²

Answer 2

To find the area of a triangle, we can use the formula $\frac{1}{2} bh$, where b is base and h is height.

We can then substitute the variables with our measurements. We then end up with an equation of$\frac{1}{2} * 15 \frac{1}{4} * 18$. Well, we can multiply one half with 18 to get 9, and all we need to do is multiply $15 \frac{1}{4}$ with 9.

We get the grand total of 137.25 inches.
