Answer:

side 1: 1.6

side 2: 2.3

side 3: 2.6

Step-by-step explanation:

side 1: 2x - 3

side 2: x

side 3: 2/3(x + 2x - 3) = 2x-2

(2x - 3) + x + (2x - 2) = 6.5

5x - 5 = 6.5

5x = 11.5

x = 2.3

side 1: 1.6

side 2: 2.3

side 3: 2.6

Answer: The length is 12 feet and the width is 4 feet.

Step-by-step explanation:

Let L represent the length of the bedroom closet.

Let W represent the width of the bedroom closet..

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the bedroom closet is 32 ft. This means that

2(L + W) = 32

Dividing through by 2, it becomes

L + W = 32/2

L + W = 16

The area of the bedroom closet is 48 ft². This means that

LW = 48 - - - - - - - -- - - - - - 1

Substituting L = 16 - W into equation 1, it becomes

W(16 - W) = 48

16W - W² = 48

W² - 16W + 48 = 0

W² - 12W - 4W + 48 = 0

W(W - 12) - 4(W - 12) = 0

W - 12 = 0 or W - 4 = 0

W = 12 or W = 4

L = 16 - 4 = 12
