The length of your garden must exceed the width of the garden by 3 feet. you only have 58 feet of fencing to go around the perimeter. if you use all the fencing, what will be the dimensions of your garden?

First let us represent

x-width

x+3-length

Since it has a width and length, we can say it is a rectangle so the formula for the perimeter of it is 2 (l+w)

p=2 (l+w)

58=2 (x+3+x)

58 = (2x+3) 2

58=4x+6

52=4x

x=13

the width is 13 and the length is 16
