Question

the area of the triangle below is 13.42 square inches. what is the length of the base? 4.4 in

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $A$ is area, $b$ is base and $h$ is height.

Step2: Rearrange formula for base

We can rewrite the formula as $b = \frac{2A}{h}$.

Step3: Substitute values

Given $A = 13.42$ square - inches and $h=4.4$ inches. Substitute into the formula: $b=\frac{2\times13.42}{4.4}$.

Step4: Calculate

First, $2\times13.42 = 26.84$. Then, $\frac{26.84}{4.4}=6.1$ inches.

Answer:

$6.1$ inches
