Answer:
The length of the rectangular playing field is 177 yards and the width is 46 yards
Step-by-step explanation:
Let
x -----> the length of the rectangular playing field
x -----> the width of the rectangular playing field
we know that
The perimeter of the rectangular playing field is
P=2(x+y)
P=446 yd
so
446=2(x+y) ------> equation A
x=4y-7 -----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
446=2(4y-7+y)
223=5y-7
5y=223+7
5y=230
y=46
Find the value of x
x=4(46)-7
x=177
therefore
The length of the rectangular playing field is 177 yards and the width is 46 yards
