Question

name area of a trapezoid period date 1) a= 2) a= 3) a= 4) a= 5) a= 6) a= 7) a= 8) a= 9) a=

Explanation:

Step1: Recall trapezoid area formula

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.

Problem 1

Given $b_1 = 4$ ft, $b_2 = 10$ ft, and $h = 11$ ft.

Step2: Substitute values into formula

$A=\frac{(4 + 10)\times11}{2}=\frac{14\times11}{2}=7\times11 = 77$ square feet.

Problem 2

Given $b_1 = 3$ miles, $b_2 = 5$ miles, and $h = 2$ miles.

Step3: Substitute values into formula

$A=\frac{(3 + 5)\times2}{2}=8$ square miles.

Problem 3

Given $b_1 = 1$ mm, $b_2 = 5$ mm, and $h = 8$ mm.

Step4: Substitute values into formula

$A=\frac{(1 + 5)\times8}{2}=\frac{6\times8}{2}=24$ square mm.

Problem 4

(No values provided in clear way in the image, assuming values from the trapezoid: if $b_1 = 4$ in, $b_2$ (not clear), $h$ (not clear), we can't solve without full info)
