Question

A rectangular field is four times as long as it is wide. If the perimeter of the field is 560 yards, what are the field’s dimensions?

Answer 1

Width=56 yards

length=224 yards

Explanation:

let:

Width=x

length= x*4= 4x

perimeter = 2*x + 2*4x

working

`(x * 2) + (4x * 2) = 560`

`2x + 8x = 560`

`10x = 560`

`(10x)/(10) = (560)/(10)`

`x = 56`

`4x = 56 * 4 = 224`

width =56 yards

length = 224 yards
