Question

HELP PLEASE! The perimeter is 22. How much bigger is the longest side than the shortest side?

I asked this question two hours ago, and since then, I haven't recived any help. I don't mean to sound demanding and I understand that there are millions of users here, but it seems it's been a while since someone's answered this, and I can't figure it out.

Answer 1

`(52)/(7)`
`units`

Explanation:

Add up all the sides.

(2a - 3) + (3a + 1) + 2a = 7a - 2

Lets set it equal to 22 since it is the perimeter

7a - 2 = 22

add 2 both sides

7a = 24

a =
`(24)/(7)`

From the image, you can tell that 2a - 3 is the shortest side and 3a + 1 is the longest side.

(3a + 1) - (2a - 3)

Substitute
`(24)/(7)` in for a.

You should be able to get
`(52)/(7)` units.
