Question

On a diagram of the arena, the car park’s length is 15 cm. The scale is 1:100. What is the actual length of the car park in metres?

Answer 1

15*100 = 1500 cms
= 15 meters

Answer 2

The actual length of the car park is 15 meters.

Explanation:

On the diagram, the car park's length is 15 cm.

Suppose, the actual length of the car park is
`x` cm.

The scale ratio is
`1:100`

According to the scale ratio....

`(15)/(x)=(1)/(100)\\ \\ x(1)=15(100)\\ \\ x= 1500`

Now, we know that 1 cm = 0.01 meter

So, 1500 cm =
`(1500* 0.01)meters = 15 meters`

Thus, the actual length of the car park is 15 meters.
