*The perimeter of a rectanle is 40cm. The width is 8cm less than the length. Find the width and the length.*

The answer I got from guessing is Length 14 Width 6. Can someone help me use the formula to get the rightanswer to this

That's messy, meaning a teacher could deduct marks...stahl7639 said:I was going by this to figure out my answer:

2L+2W= 40

L+L+(L-8)(L-8)=40

4L-16=56

56/4= 14

14-8 = 6

Length- 14

Width- 6

Look at what Sir Skeeter did, and make sure you use that style in the future...
