Question 53763: The problem is...The length of a rectangular playing field is 5 ft less than twice its width.
If the perimeter of the playing field is 230 ft, find the length and width of the field.
I thought you would go length times width, but for some reason the added numbers are confusing me. wouldnt 5x-2x=230?

Length times width is the area, we want the perimeter, which is the sum of all the lengths of the sides (width+width+length+length).
Let's call width x. If the length is 5 less than twice x, it'll be 2x-5. Now we equal the perimeter to 230 and solve:
x+%2B+x+%2B+2x-5+%2B+2x-5+=+230
4x+-+10+=+230
4x+=+240
x+=+60
If the width is 60 ft, the length will be 2*60 - 5 = 115 ft.
