Question

PLEASE HELP

Answer 1

Answer:

D.) 200ft²

Step-by-step explanation:

The formula for the area of a trapezoid:

$A=\frac{1}{2} (b_{1}+b_{2})h$

where:

• $b_{1}$ and $b_{2}$ are the bases
• h is the height

Insert the given values:

$A=\frac{1}{2}(16+24)*10$

Simplify the equation using PEMDAS. Simplify parentheses:

$A=\frac{1}{2}*40*10$

Simplify multiplication:

$A=\frac{1}{2}* 400$

Simplify multiplication. Use the rule $\frac{a}{b}*c=\frac{ac}{b}$ :

$A=\frac{1*400}{2}\\\\A=\frac{400}{2}$

Simplify division:

$A=200$

The area is 200ft²
