Question 981345
.
A=Area=1000yd^2; L=length; W=width=L-30yds
.
A=LW
1000yds^2=(L)(L-30yds)
1000yds^2=L^2-30L
0=L^2-30L-1000
0=(L-50)(L+20)
L-50=0 OR L+20=0
L=50 yards OR L=-20 yards
ANSWER 1: The length of the field is 50 yards.
W=L-30yds=50yds-30yds=20yds ANSWER 2: The width of the field is 20 yards.
.
The field is 50 yards by 20 yards.
