Question

dante is ordering wood flooring for his bedroom which is shaped like a trapezoid if flooring materials cost $5 per square foot how much should he expect to pay for the materials

Answer 1

$650 because if you split the shape into a square and. a triangle you get 100 ft + 30 ft, so, you multiply 130×5 to get an answer of $650

Answer 2

Answer:

All materials to cover the whole area would cost $650.

Step-by-step explanation:

The formula to find the area of a trapezoid is

$A=\frac{a+b}{2} \times h$

Where $a$ is the largest base, $b$ is the smallest base, and $h$ is the height. So, in this problem each variable would be

$a=16ft\\b= 10ft\\h=10ft$

Replacing these values, we have

$A=\frac{a+b}{2} \times h\\A=\frac{16ft+10ft}{2} \times 10ft\\ A=\frac{26ft}{2} \times 10ft\\ A=13 ft \times 10ft\\A=130 ft^{2}$

So, if each unit of area cost $5, we just need to multiply it with the total area of the trapezoid

$C=130ft \times 5 \ =650$

Therefore, all materials to cover the whole area would cost $650.
