A school is building a rectangular soccer field that has an area of 6000 square yards. The soccer field must be 40 yards longer
kogti [31]

Area is 6000 yd2

LW = 6000

field must be 40 yards longer than its width

L = W + 40

Replace L with W+40 in 1st equation to solve for Width

(W+40)(W) = 6000

W2 + 40W - 6000 = 0

This is a quadratic but is factorable

Factors of -6000 that add to 40 are (100)(-60)

(W+100)(W-60) = 0

W = -100   or   W = 60

Since the width will not be negative discard -100

The width is 60 yards

Length is W+40 = 100 yards
