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

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

Explanation:

The formula to find the area of a trapezoid is

`A=(a+b)/(2) * 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=(a+b)/(2) * h\\A=(16ft+10ft)/(2) * 10ft\\ A=(26ft)/(2) * 10ft\\ A=13 ft * 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 * 5 \$=650 \$`

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