The width of a high school soccer field is 45 yards shorter than its length

A) W=L-45

b) a=L*W

Use the equation we created in part a and plug it into the area formula.

a=L * (L-45)

9000=L (L-45)

9000=2L-45L

9000=-43L

L = - 9000/43

Now to find the width, plug in the length back into the first equation, in part a.

W = (-9000/43) - 45

W = - 10935/43 (Sorry if you need it in decimal form. Just plug it into a calculator : D)
