Tracy needs to find the length and width of the equipment storage room where she works. the room is 2 m longer than it is wide. it’s perimeter is 24 m. what is the width in meters?

Let the width be w. Therefore we can right the length as w+2=l. We know the formula for perimeter is 2w + 2l = P. We can fill this formula in to help solve this problem with the pieces we have.

2w+2(w+2)=24

2w+2w+4=24

4w=20

w=5

So, we now know the width of the room. Next, lets plug that into the perimeter equation again and solve for the length now.

2(5) + 2l = 24

10 + 2l = 24

2l = 14

l=7

So the width is 5m and the length is 7m.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
