Question

The scale of building plan is 1cm to 50cm. Represented length of the bedroom is 9.2cm, find the actual length​

Answer 1

Answer:

460cm

Step-by-step explanation:

since for 1cm actual length is 1×50 = 50cm,

for 9.2 cm, actual length of bedroom is 9.2×50 = 460cm

Answer 2

For the given scale, the actual length of the bedroom will be 460 cm.

Given,

The scale of a building plan:

1 cm to 50 cm.

Represented length of the bedroom = 9.2 cm.

To find,

The actual length of the bedroom.

Solution,

The scale on a plan or a map is defined as the ratio of distance or length on the plan to the distance on the ground or the actual length of a real object.

For example, say the scale on a plan is 1 cm to x cm. It is written as

1 : x, and

then, the actual length will be 'x' times the length shown on the plan.

Here, we can see that the scale is given to be

1 cm to 50 cm.

So, from the above definition, we can say that the actual length or distance will be 50 times the length on the plan.

Given bedroom length = 9.2 cm.

Thus,

the actual length of the bedroom = 9.2 × 50

⇒ the actual length of the bedroom = 460 cm.

Therefore, for the given scale, the actual length of the bedroom will be 460 cm.
