Question

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

Answer 1

a Rectangle has 4 sides so let x= width and 2x equal length so it should read as follows: 2(2x)+ 2(x)=216 (perimeter)
4x+2x=216
6x=216
divide by 6 both sides to isolate x
x=36
check equation
2(36)=72
2(72)=144
72 +144=216

Answer 2

236(56)123)97(50)12(4
