Question

what is the area of the trapezoid? 0.9 ft. 1.2 ft. 1.1 ft. 0.5 ft. square feet

Explanation:

Step1: Recall area formula for trapezoid

The formula for the area of a trapezoid is $A=\frac{(b_1 + b_2)h}{2}$, where $b_1$ and $b_2$ are the lengths of the parallel - sides and $h$ is the height. Here, $b_1 = 0.9$ ft, $b_2=0.5$ ft, and $h = 1.1$ ft.

Step2: Substitute values into formula

$A=\frac{(0.9 + 0.5)\times1.1}{2}$
First, calculate the sum of the parallel sides: $0.9+0.5 = 1.4$ ft. Then, multiply by the height: $1.4\times1.1=1.54$ square - feet. Finally, divide by 2: $A=\frac{1.54}{2}=0.77$ square feet.

Answer:

$0.77$
