1)The dimensions you  are solving for

length of the rectangular room

width of the rectangular room

2)Now let the length be L and the width be w then

the perimeter is 2L+2W

2L+ 2W  = 24(1)

Also, "Twice the length decreased by three times the width is 4 feet" can be written as

2L - 3W = 4(2)

Solving (1) and (2) by elimination method, by subtraction

2L+ 2W  = 24

2L - 3W = 4

(-)    (-)       (-)

0L  +5W = 20

5W = 20

W = 4(3)

Now by substitution method,substituting (3) in(1)

2L+ 2(4)  = 24

2L + 8 = 24

2L = 24 -8

2L = 16

L = 8

Substituting in the original equation and rechecking the perimeter

=2(8) + 2(4)

=16 + 8

= 24

Thus the found dimensions are correct

3)The length of the room is 8 feet and the width of the room is 4 feet.
