Question

if Mr. arenth wants to put new carpeting in the room shown, how many square feet should he order L= 14ft. W = 6c-8ft. L= 5+3c ft.

Answer 1

By definition, the area is given by:

`image`

Where,

w: width

l: length

We have two expressions for the length:

`image`

Since the length is the same, we equate both expressions:

`image`

From here, we clear the value of c:

`image`

`image`

Then, we have that the width is given by:

`image`

Substituting the value of c we have:

`image`

Finally, the area is given by:

`image`

Answer:

he should order 140 square feet
