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=(1)/(2)\cdot b\cdot h`

we have

A=10.98 ft2

h=3.6 ft

substitute the given values

`\begin{gathered} 10.98=(1)/(2)\cdot b\cdot3.6 \\ \\ b=(10.98\cdot2)/(3.6) \\ \\ b=6.1\text{ ft} \end{gathered}`

answer is 6.1 ft
