Answer
The base of the triangle is $12$ feet.
Work Step by Step
Let the base of the triangle is $=b$.
Height of the triangle is $h=8$ feet
Area of the triangle $A=48$ square feet.
Area formula for the triangle is
$\Rightarrow A=\frac{1}{2}bh$
Substitute $48$ for $A$ and $8$ for $h$.
$\Rightarrow 48=\frac{1}{2}b(8)$
Simplify.
$\Rightarrow 48=4b$
Divide each side by $4$.
$\Rightarrow 12=b$
Hence, the base of the triangle is $12$ feet.
