Solving math problems for Grade 4, page 82 VBT book 2, Practical Exercises (Continued), Exercise 151
1. Solve Problem 1 - Math Exercise Book Grade 4 Exercise 2 Page 82
Task Description:
The length of the classroom table is 3 meters. Please draw a line segment representing that table length on a map with a scale of 1:50.
Calculate
3m = ....cm
The length of the table on the map is:....
Draw a line segment representing the length of the classroom table
Solution Method
- Convert 3m = 300cm (or 3m = 3000mm).
- Calculate the length of the table on the map by dividing 300cm by 50 (or dividing 3000mm by 50).
- Draw a line segment with the calculated length from the previous step on the map.
Answer
Convert 3m = 300cm
The length of the table on the map is: 300 : 50 = 6cm
Draw a line segment of length 6cm on the map. This represents the length of the table on the map with a scale of 1:50.
2. Solve Problem 2 - Math Exercise Book Grade 4 Exercise 2 Page 82
Task Description:
The floor of a classroom is a rectangle with a length of 8m and a width of 6m. Please draw a rectangle representing the classroom floor on a map with a scale of 1:200.
Calculate
8m = ...cm
6m = ....
The length of the rectangle on the map is:....
The width of the rectangle on the map is:....
Draw a rectangle representing the classroom floor
Solution Method
- Convert the measurements of length and width to units in meters.
- For the map with a scale of 1:200, to find the length on the map of the sides, take the actual length of those sides (in meters) and divide by 200.
- Draw a rectangle with the dimensions found above.
Answer
8m is equivalent to 800cm
6m is equivalent to 600cm
The length of the rectangle on the map is:
800 : 200 = 4(cm)
The width of the rectangle on the map is:
600 : 200 = 3(cm)
Draw a rectangle representing the classroom floor
