Question

On the blueprint of a house,
35
millimeters represents
10
meters. The actual length of the living room is
9
meters. What is its length on the blueprint?

Answer 1

One way to solve the problem is to set up a ratio.

 

We know 35 mm is equivalent to 10 m. We want to find x which is the number of mm that equals 9 m.

35 mm/10 m = x/9 m

 

If we cross multiply, 10x = (35*9)

10x = 315

 

Then divide 10 on both sides. x = 31.5 mm
