The perimeter of a rectangle is 28 inches and the length is 9 inches. what's the area?

To find the area of a rectangle, you must multiply the length and the width.

We are given the length which is 9 inches, now we must find the width.

To find the perimeter, the formula is l + w + l + w = 28. Now we can replace

the l with 9. 9 + w + 9 + w = 28.

We can then find the width.

w + w = 28 - 9 - 9

w + w = 10

w + w = 10

w + w can also be represented as 2w.

2w = 10

w = 10 / 2

w = 5

We now have our length and our width,

l = 9 inches

w = 5 inches

So now we must multiply the two to get the area.

l x w = a

9 x 5 = a

45 = a

And there we have it, your area is 45 inches.

Hope this helps, if my answer or explanation is wrong

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
