Asoccer field is 70 yards shorter 3 times its width. its perimeter is 380 yards. find the length and width of the field

Let
x> the length of a soccer field 
y> the width of a soccer field 

we know that
x=3y-70> equation 1
perimeter=2*[x+y]> 380=2x+2y> equation 2

substitute 1 in 2
380=2*[3y-70]+2y> 380=6y-140+2y> 8y=520> y=65 yd
x=3y-70> x=3*65-70> x=125 yd

the answer is
the length of a soccer field is 125 yd
the width of a soccer field is 65 yd

Ithink it’s d as the answer.
