You can put this solution on YOUR website! What is the length of a room that is 2 meters longer than it is wide and the
perimeter is 24?
:
let x = the width
let L = the length
:
"length of a room that is 2 meters longer than it is wide"
L = x + 2
:
Perimeter:
2L + 2x = 24
:
Replace L with (x+2)
2(x+2) + 2x = 24
2x + 4 + 2x = 24
4x = 24 - 4
4x = 20
x =
x = 5 m is the width
then
5 + 2 = 7 m is the length

Check solution by finding the perimeter using these values
2(7) + 2(5) = 24
