Question

10 ft 10 ft 9.17 ft 8 ft

Explanation:

Step1: Recall triangle - area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

From the figure, the base $b = 8$ ft and the height $h=9.17$ ft.

Step3: Calculate the area

Substitute $b = 8$ and $h = 9.17$ into the formula: $A=\frac{1}{2}\times8\times9.17$. First, $\frac{1}{2}\times8 = 4$, then $4\times9.17=36.68$ square - feet.

Answer:

$36.68$ square feet
