The perimeter of the kitchen is 528 inches. If the width of the kitchen is 120 inches, what is the length of the kitchen?

Answer :

Final answer:

The length of the kitchen, given a perimeter of 528 inches and a width of 120 inches, is calculated to be 144 inches.

Explanation:

The student is asked to find the length of the kitchen given its perimeter and width. The formula to find the perimeter of a rectangle is P = 2 *(length + width). In this case, the perimeter (P) is 528 inches and the width is 120 inches. We can plug these into the formula and solve for length.

528 = 2*(length + 120)

Divide both sides of the equation by 2: 264 = length + 120

Then, subtract 120 from both sides: 144 = length

So, the length of the kitchen is 144 inches.

Answer: 144 inches.


Step-by-step explanation:

1. To solve this problem you must remember the formula for calculate the perimeter of a rectangle, which is shown below:

[tex]P=2l+2w[/tex]

Where [tex]l[/tex] is the lenght and [tex]w[/tex] is the width.

2. You know the perimeter and the width, then you can solve for the length, as following:

[tex]P-2w=2l\\l=\frac{P-2w}{2}\\l=\frac{(528in)-(2*120in))}{2}\\l=144in[/tex]
