Question

what is the missing length? 28 ft area = 252 ft² v = feet

Explanation:

Step1: Recall triangle - area formula

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

Step2: Identify known values

Here, $A = 252$ square - feet and $h=28$ feet. Let the base be $v$.

Step3: Substitute values into formula

We have $252=\frac{1}{2}\times v\times28$.

Step4: Solve for $v$

First, simplify the right - hand side of the equation: $\frac{1}{2}\times28 = 14$. So the equation becomes $252 = 14v$. Then, divide both sides by 14: $v=\frac{252}{14}=18$.

Answer:

18
