It is 31 inches because 1 ft. is 12 inches so 2 ft. is 24 inches then add 7 inches. It is pretty obvious,no offense.
Assume that you want to write that value in inches. Remember that 1 ft = 12 inches. Then... 3 ft = 36 inches Add that by 7.2 to get 43.2 inches.
6.5 - Since there are 12-inches in a foot, 6-inches is half of a foot or 0.5-ft. From there you just add 6-ft + 0.5-ft to get your answer.
Well you have to multiply 5 x 12 (12 in= 1 ft) and then add 2 in, and your total is 60 in
