Question

Help plz, and explain why. Thank you!!! :)))

Answer 1

Answer:

The relative length will be 5 inches.

Step-by-step explanation:

This is a basic question on Dilation. In dilation, the relative dimensions of an object gets increased/reduced by a scaling factor 'k'. Herein,

Scale used : 1 inch = 4 feet => 1/4 inch = 1 feet.

Therefore, the relative dimensions in the sketch will be 1/4 times their original lengths.

Hence, relative length of the room with original length being 20 feet is = (1/4)*20 = 5 inches.

Answer 2

Answer:

The length of the room in the drawing is 5 inches.

Step-by-step explanation:

Kenneth measured a hotel and made a scale drawing the scale he used was 1 inch= 4 feet.

The actual length of a room in the hotel is 20 feet.

Now, to find the length of the room in the drawing.

Let the length of the room in the drawing be x

The actual length of the room = 20 feet.

The scale used in drawing is 1 inch = 4 feet.

As, 1 inch is equivalent to 4 feet.

Thus, x is equivalent to 20 feet.

Now, to get the length of the room in the drawing we use cross multiplication method:

1/4 = x/20

By cross multiplying we get:

20 = 4x

Dividing both sides by 4 we get:

5 =

: x = 5 inches

Therefore, the length of the room in the drawing is 5 inches.
