Find the scale of the construction drawing of the new school, if all the sizes of the objects have been reduced by 50 times.

Find the scale of the construction drawing of the new school, if all the sizes of the objects have been reduced by 50 times. What are the dimensions in the drawing: 1) corridor 28 * 3 m; 2) a reading room with an area of 52 m2 if its length is 6.5 m?

Find the dimensions of the corridor on the map – divide the length and width of the corridor by 50:

28: 50 = 0.56 m = 56 cm – the length of the corridor;

3: 50 = 0.06 m = 6 cm – the width of the corridor.

To determine the size of the reading room in the drawing, we first find its width – we divide its area by length:

52: 6.5 = 8 m reading room width.

Divide its dimensions by 50:

6.5: 50 = 0.13 m = 13 cm length of the reading room;

8:50 = 0.16 m = 16 cm width of the reading room.

Answer: the corridor is 56 cm by 6 cm, the reading room is 13 cm by 16 cm.
