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

Answer:

The actual length of the car park is  15 meters.

Step-by-step 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....

$\frac{15}{x}=\frac{1}{100}\\ \\ x(1)=15(100)\\ \\ x= 1500$

Now, we know that  1 cm = 0.01 meter

So, 1500 cm = $(1500\times 0.01)meters = 15 meters$

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