Question

HELP! A rectangular athletic field is twice a long as it is wide. If the perimeter of the athletic field is 216 yards, what are its dimensions?

Answer 1

area of field is =2(l+b)
where l is length b is breadth
here l=2b

so
(2(2b+b)=216
6b=216
b=36

Answer 2

I'm still a bit confused...I tried using the equation 2l+2w

Answer 3

its the same
2l+2w =2(l+w)

only diff is i called width as b you call it as w

Answer 4

gt it?

Answer 5

Yeah I think I got it. Thank you!
