Guide to solving Exercise on page 30 Math Grade 5 includes solving methods

1. Solving problem 1 page 30 Math Grade 5 textbook

Problem statement:

Solution method:

Students should review the table of area measurement units they have learned, noting that two consecutive units will be greater (or less) by 100 times.

2. Solving problem 2 page 30 Math Grade 5 textbook

Solution method:

>>> Refer back to detailed instructions in the Exercise 3 solution on pages 28, 29 Math Grade 5 textbook.

3. Solving problem 3 page 30 Math Grade 5 textbook

Problem statement:
A rectangular room with a length of 6m and a width of 4m is to be floored with wood. How much money is required to buy wood for the entire room, given that the price of 1m² of flooring wood is 280,000 dong?

Solution method:

- To find the floor area of the room, apply the formula for the area of a rectangle: S = length x width (where length is 6m and width is 4m)

- To calculate the amount of money needed to floor the entire rectangular room, multiply the floor area of the room (previously calculated) by the price of 1m² of wood flooring.

Answer:
The floor area of the room is:
6 x 4=24 (m²)
The amount of money to buy wood for flooring is:
280000 x 24= 6720000 (dong)
Answer: 6720000 dong.

4. Solving problem 4 page 30 Math Grade 5 textbook

Problem statement:
A rectangular plot of land has a length of 200m and a width equal to 3/4 of the length. What is the area of that plot of land in square meters? In hectares?

Solution method:

- Step 1: Calculate the width of the plot of land by multiplying the length by 3/4 (because the width is 3/4 of the length)

- Step 2: Calculate the area of the plot of land by applying the formula for the area of a rectangle: Multiply the width (previously calculated) by the length.

- Step 3: Convert the length measurement unit from square meters to hectares.

Frequently Asked Questions

What are the steps to solve problem 1 in the Math Grade 5 textbook?

To solve problem 1 on page 30 of the Math Grade 5 textbook, students should first review the table of area measurement units. Then, they should understand that each consecutive unit differs by a factor of 100. This foundational knowledge is crucial for accurately calculating areas in various units.

How can students calculate the area of a rectangular room for flooring?

Students can calculate the area of a rectangular room by using the formula for the area of a rectangle, which is length multiplied by width. For instance, if the room's length is 6 meters and its width is 4 meters, the area would be 6 x 4, equating to 24 square meters.

What is the method to find the cost of flooring for a room?

To find the cost of flooring a room, first calculate the area using the formula for the area of a rectangle. Then, multiply this area by the price per square meter of the flooring material. For example, if flooring costs 280,000 dong per square meter and the area is 24 square meters, the total cost will be 6720000 dong.

How do you convert square meters to hectares in mathematical calculations?

To convert square meters to hectares, divide the area in square meters by 10,000, since 1 hectare is equivalent to 10,000 square meters. This conversion is essential when dealing with larger plots of land to ensure accurate measurements and calculations.
