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

Answer:

140 sq. ft

Step-by-step explanation:

Given information: L= 14ft. W = 6c-8ft. L= 5+3c ft.

Equate the values of length.

$5+3c=14$

Subtract 5 from both sides.

$3c=9$

Divide both sides by 3.

$c=3$

The value of c is 3.

The width of the carpet is

$W=6c-8$

$W=6(3)-8$

$W=18-8$

$W=10$

The width of the carpet is 10 ft.

The area of a rectangle is

$A=length\times width$

The area of carpet is

$A=14\times 10$

$A=140$

Therefore, Mr. arenth should order carpet of 140 sq. feet carpet.

Answer 2

If you put 5+3c=14 and solve you will get c=3 so then you put 3 in for c for the width equation. you then get 10 ft for the width. if you multiply 10 ft by 14 ft you would get the answer of 140 sq ft
