Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual width measurement at the base of the Washington Monument is about 55 ft. About how tall is the Washington Monument?
Accepted Solution
A:
Using how tall it is over how wide =>tall/wide The model 15in/1.5in The actual x/55ft
Convert everything into the same units so 55ft to inches There are 12in in 1ft 55ft * 12in/1ft The ft cross out leaving in 55*12in= 660 in
So 15in/1.5in = x/660in Now solve for x my multiplying both side by 660in 660in *15in/1.5in=x x= 6600in tall
