The length of a rectangular playing feild is 5ft lessthan twice the width. If the perimeter of the playing field is 230ft, what is the length of the playing field.
x=length
y=width
we know:
2x+2y=230
x+5=2y
Solve using systems.
Easiest is to substitute x+5 for 2y into the first equation:
2x+x+5=230
then solve for x
