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

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
