a) 1,269 feet
b) 1,431 feet
c) 4,131 feet
d) 3,969 feet

work:

First set up your proportion

part. 53. x

= =

whole 100. 2700

I'm choosing to cross multiply but there are different methods

so 100x= 143100

then you have to get x by itself so you divide each side by a hundred and x= 1431

here ya go

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
