Question

A scale on a blue print drawing of a house shows that 10 1010 centimeters represents 2 22 meters. What number of actual meters are represented by 18 1818 centimeters on the blue print?

Answer 1

On Blue print 18 centimeters represents 3.6 meters.

Explanation:

Given:

Scale is 10 cm = 2 m

We need to find the number of actual meters are represented by 18 1818 centimeters on the blue print.

Solution:

Now we know that;

10 cm = 2 m

so 1 cm = Number of meters in 1 cm.

By using Unitary method we get;

Number of meters in 1 cm =
`(2)/(10)=0.2\ m`

Now we know that;

1 cm = 0.2 m

18 cm = Number of meters in 18 cm.

Again by using Unitary method we get;

Number of meters in 18 cm =
`0.2* 18 = 3.6\ m`

Hence On Blue print 18 centimeters represents 3.6 meters.
