Which equation can be used to find the width of the field above if the perimeter is 280 yard (above) the field is ×,and the width of the field is 20.

Answer :

apologiabiology
P=2(L+W)
P=280
W=20 (yards I assume)

280=2(L+20)
divideboth sides by 2
140=L+20
minus 20
120=L

length=120 yards

equation is
P=2(L+W)
 or

280=2(x+20)
