A = 13.95 ft^2
l = x
b = x + 1.4

a = l × b

13.95 = x × ( x + 1.4 )

13.95 = 3.1 × ( 3.1 + 1.4 )

13.95 = 13.95

length = 3.1
width = 4.5

murzikaleks [220]

2 hours of a 60mph is literally 60 miles per hour so for 2 hours its 120miles plus an addition of 40 miles how ever its half an hour so he gained 20 so 140 should be the answer if im not mistaken.
