X=4 ........................................
X=5, should be right correct me if i’m wrong.
27 yards
perimeter= l+l+w+w
9.5+9.5+4+4=27
5(4x-1) = 80
20x - 5 = 80
20x - 5 + 5 = 80 + 5
20x = 85
20x/20 = 85/20
X = 85/20
X = 17/4 if reduced to lowest terms by dividing both the top and bottom number by 5.
