Draw a plan of a room 90m2 using a scale 1cm :3m

To draw a plan of a room using a scale, you will need to follow these steps:

1. Measure the length and width of the room in meters. Let's say the length is 10 meters and the width is 9 meters.

2. Determine the scale you want to use. In this case, you mentioned a scale of 1cm:3m. This means that 1 centimeter on your drawing will represent 3 meters in real life.

3. Calculate the size of the room on your drawing. Divide the length and width of the room by the scale. In this case, divide 10 meters by 3 to get the length on the drawing, which is approximately 3.3 centimeters. Divide 9 meters by 3 to get the width on the drawing, which is approximately 3 centimeters.

4. Take a blank sheet of paper, a ruler, and a pencil. Use the ruler to draw a straight line at the bottom of the paper. This line will represent one side of the room.

5. Measure 3.3 centimeters from one end of the line and mark it. This mark represents the length of the room.

6. Draw a vertical line starting from the mark you made earlier. This line represents the height of the room.

7. Measure 3 centimeters to the right from the top end of the vertical line and mark it. This mark represents the width of the room.

8. Draw a horizontal line starting from the mark you made earlier. This line completes the outline of the room.

9. If there are any doors, windows, or other features in the room, measure their sizes accurately and place them in the drawing accordingly. Remember to adjust their dimensions based on the scale you are using.

10. Add any other details you want to include, such as furniture or fixtures, to complete your room plan.

By following these steps, you should be able to draw a plan of a room that is 90 square meters using a scale of 1 centimeter to 3 meters.
