Question 818454
x = width
x - 4 = length


Perimeter of a rectangle = 2(width) + 2(length)


2x + 2(x - 4) = 412 {substituted into perimeter formula}
2x + 2x - 8 = 412 {used distributive property}
4x - 8 = 412 {combined like terms}
4x = 420 {added 8 to each side}
x = 105 {divided each side by 4}
x - 4 = 101 {substituted 130, in for x, into x - 4}


width = 105 m
length = 101 m
