Answer:
Width = 46 yards, Length=175 yards.
Step-by-step explanation:
Perimeter of rectangle = 2(length) +2(width)
We know that the length is 4width-9, so we can substitute that in for the length.
442= 2(4w-9)+2w, Next distribute
442=8w-18+2w, Now add like terms
442=10w-18, Move 18 to the other side
460=10w, solve for w
width= 46 yards.
Now we have 442=2(length)+2(46), subtract 92 to the left
350=2(length), divide by 2
Length= 175 yards.
Check your work with P=2(175)+w(46)
P=442 yards.
