Problema Solution
A builder is reading blueprints for a mansion. The blueprint indicates 5 inches represents 9 feet. On the blueprint, a wall is 55 inches. What is the actual length of the wall?
Answer provided by our tutors
let 'x' represent the actual length of the wall in inches
1 ft = 12 in
9 ft = 12*9 in
9 ft = 108 in
5 : 108 = 55 : x
by solving we find:
x = 1188 in
click here to see the step by step solution of the equation:
1188 in = 1188/12 ft = 99 ft
the actual length of the wall is 99 feet.
