Question

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

Answer 1

Answer:

3.6 meters are represented by 18 centimeters on the blueprint.

Step-by-step explanation:

Given:

A scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters.

Now, to find the actual meters represented by 18 centimeters.

Let the actual meters represented by 18 centimeters be $x.$

As, given the scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters.

So, 10 centimeters equivalent to 2 meters.

Thus, 18 centimeters equivalent to $x.$

Now, to solve by using cross multiplication method:

$\frac{10}{2}=\frac{18}{x}$

By cross multiplying we get:

$10x=36$

Dividing both sides by 10 we get:

$x=3.6\ meters.$

Therefore, 3.6 meters are represented by 18 centimeters on the blueprint.
