CPM Homework Help : CC2MN Problem 4-78

Dante is ordering wood flooring for his bedroom, which is shaped like a trapezoid (shown at right). If the flooring materials cost $\$5$ per square foot, how much should he expect to pay for the materials?

Step 1:

First, you must find the area of the trapezoid, since this in the amount of flooring material Dante will need.

$\frac{1}{2} (10)(16 + 10) = 5(26) = 130$ square feet

Step 2:

Next, multiply the area by $\$5$ to find the cost of the necessary flooring materials. $(130)(5)=\$650$

Answer:

$\$650$

A trapezoid whose right side is perpendicular to the parallel sides, labeled as follows: top, 10 ft, right side, 10 feet, bottom, 16 ft.
