Question

I need helping finding out the answer (don’t mind my last name so n the picture)

Answer 1

Answer:

$\text{base}=\text{ 9.5 inches}$

Step-by-step explanation:

The area of a triangle is represented by the following equation;

$\text{Area}=\frac{\text{base}\cdot\text{height}}{2}$

Then, if the height is 82.65 square inches and the height is 17.4 inches, solve for the base:

$\begin{gathered} 82.65=\frac{1}{2}\cdot b\cdot17.4 \\ b=\frac{82.65\cdot2}{17.4} \\ b=\frac{19}{2} \\ b=9.5\text{ inches} \end{gathered}$
