Question

1) Find the base of a triangle with height Sift and area 17.5 ft? ba

Answer 1

The formula to find the area of a triangle is:

$A=\frac{1}{2}b\cdot h$

As you know the area and height, solve the equation for b:

$\begin{gathered} \frac{A}{h}=\frac{1}{2}b \\ \\ \frac{2A}{h}=b \end{gathered}$Then, the base of the give triangle is: 7 ft$\begin{gathered} b=\frac{2(17.5ft^2)}{5ft} \\ \\ b=\frac{35}{5}ft \\ \\ b=7ft \end{gathered}$
