Using each of the following scales, find the dimensions in a blueprint of an 8ft-by-12ft room.

1. 1 in.:2ft

2. 1 in.:4ft

I don't get this.

1.

1 in = 2 ft Divide both sides with 2

0.5 in = 1 ft

0.5 * 8 = 4 in

0.5 * 12 = 6 in

4 in by 6 in

2.

1 in = 4 ft Divide both sides with 4

0.25 in = 1 ft

0.25 * 8 = 2 in

0.25 * 12 = 3 in

2 in by 3 in

1. Using the scale 1 in.:2ft, we can convert the dimensions of the room as follows:

8 ft x 2 ft/in. = 16 in. (width)

12 ft x 2 ft/in. = 24 in. (length)

Therefore, the dimensions of the 8ft-by-12ft room on the blueprint would be 16 in. by 24 in.

2. Using the scale 1 in.:4ft, we can convert the dimensions of the room as follows:

8 ft x 4 ft/in. = 32 in. (width)

12 ft x 4 ft/in. = 48 in. (length)

Therefore, the dimensions of the 8ft-by-12ft room on the blueprint would be 32 in. by 48 in.

To find the dimensions of an 8ft-by-12ft room using different scales, we need to multiply the measurements of the room by the corresponding scale factor.

1. Scale: 1 in.:2ft

For this scale, every 1 inch on the blueprint represents 2 feet in real life.

To find the corresponding dimensions on the blueprint:
- Length: Multiply the length of the room (8ft) by the scale factor (2).
8ft * 2 = 16 inches
So, the length of the room on the blueprint would be 16 inches.

- Width: Multiply the width of the room (12ft) by the scale factor (2).
12ft * 2 = 24 inches
Therefore, the width of the room on the blueprint would be 24 inches.

So, using the scale 1 in.:2ft, the dimensions of an 8ft-by-12ft room on the blueprint would be 16 inches by 24 inches.

2. Scale: 1 in.:4ft

For this scale, every 1 inch on the blueprint represents 4 feet in real life.

To find the corresponding dimensions on the blueprint:
- Length: Multiply the length of the room (8ft) by the scale factor (4).
8ft * 4 = 32 inches
Therefore, the length of the room on the blueprint would be 32 inches.

- Width: Multiply the width of the room (12ft) by the scale factor (4).
12ft * 4 = 48 inches
Hence, the width of the room on the blueprint would be 48 inches.

Thus, using the scale 1 in.:4ft, the dimensions of an 8ft-by-12ft room on the blueprint would be 32 inches by 48 inches.
