Question

1. 2 ft 7 ft 2 ft 7 ft 7 ft

Explanation:

Step1: Identify the formula for the area of a trapezoid

The formula for the area of a trapezoid is $A=\frac{(a + b)h}{2}$, where $a$ and $b$ are the lengths of the parallel - sides and $h$ is the height. Here, the parallel sides are $a = 7$ ft and $b=2 + 7+2=11$ ft, and the height $h = 7$ ft.

Step2: Substitute the values into the formula

$A=\frac{(7 + 11)\times7}{2}$.
First, calculate the sum of the parallel sides: $7+11 = 18$ ft.
Then, multiply by the height: $18\times7=126$ square - feet.
Finally, divide by 2: $\frac{126}{2}=63$ square - feet.

Answer:

63 square feet
