Question

now hector wants to pave his driveway. pavement costs about $4.00 per square foot. first find the total area of the driveway. a = \square ft^2 an error has occurred. please enter a number.

Explanation:

Step1: Calculate area of the rectangle

$A_1 = 30 \times 20 = 600$ $\text{ft}^2$

Step2: Calculate area of the trapezoid

The formula for the area of a trapezoid is $\frac{1}{2}(b_1 + b_2)h$. Here, $b_1=25$ ft, $b_2=25+10=35$ ft, $h=10$ ft.
$A_2 = \frac{1}{2}(25 + 35) \times 10 = 300$ $\text{ft}^2$

Step3: Sum the two areas

$A = A_1 + A_2$
$A = 600 + 300 = 900$ $\text{ft}^2$

Answer:

$900$
