Answer 1

The door should be 1.6cm wide on the drawing.

Explanation:

1 meter is 100 centimeters.

Elena's bedroom door is 80 centimeters wide.

To find how wide it should be on the drawing, divide by 50.

`(80)/(50)` = 1.6cm

The door should be 1.6cm wide on the drawing.

Answer 2

The width of the door on the scale drawing in centimeters will be:

1.6 centimeter.

Explanation:

It is given that:

Elena’s bedroom door is 0.8 m wide.

Also,the scale drawing is in the ratio of 1 to 50 i.e. 1:50

Now, we know that:

1 meter= 100 centimeter.

Hence,

0.8 meters= 80 centimeters.

This means that:

In order to find the width of scale drawing:

We need to multiply original width of the door by 1/50.

i.e. we have:

80× 1/50 = 1.6 centimeter.

Hence, the width of the door on the scale drawing is: 1.6 centimeter.
