Question

The area of the triangle below is 10.98 square feet. What is the length of the base? 3.6 ft)

Answer 1

Remember that

the area of a triangle is equal to

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

we have

A=10.98 ft2

h=3.6 ft

substitute the given values

$\begin{gathered} 10.98=\frac{1}{2}\cdot b\cdot3.6 \\ \\ b=\frac{10.98\cdot2}{3.6} \\ \\ b=6.1\text{ ft} \end{gathered}$

answer is 6.1 ft
