You can put this solution on YOUR website! Good evening student. I hope that this solution is helpful to you.
One must use the following formula to answer the question:
p=2L+2w
as stated in the problem above p=60 and L=12 with this information we can now solve the problem.
1. substitute the known values into the perimeter formula for the variables
60=2(12)+2w
2. distribute the 2
60= 24+2w
3. subtract 24 from both sides of the equation:
60-24=24-24+2w
4. combine like terms on the left
36=2w
5. we want to isolate w, so we divide each side by 2
36/2=2w/2
the 2's on the right cancel each other out leaving:
36/2=w
6. solve for w
18=w
If you desire to check the answer, all you do is substitute all the known values into the formula and determine whether or not, they add up to 60.
2(12)+2(18)= 24+36=60
60=60 so the answer is correct.
