DS!!!........how goes it??

We can solve this with a proportion........note....5ft = 60in........so we have

60/ 2 = x / 3 where x is the actual tent length.....cross- multiply

180x = 2x divide both sides by 2

x = 90 in. = 7 + 1/2 ft

Since the ratio of the photo is 2: 60 inches, therefore,

60/2 X 3=90 inches

90/12=7.5 feet- Length of the tent.
