Question

A new youth activity center is being built in safe harbor. The perimeter of the rectangular playing field is 282 yards. The length of the field is 6 yards less thank double the width. What are the dimensions of the playing field

Answer 1

Answer:
length=92yd
width=49yd

Step by step:
2l+2w=282
l=2w-6
Plug in l
2(2w-6)+2w=282
4w-12+2w=282
6w-12=282
6w=282+12
w=294/6
w=49
Then plug in w
2l+2(49)=282
2l+98=282
2l= 184
l=92
