Answer:
Solution for Exercise 4 on Page 47 Math Grade 5
Problem:
A rectangular playground has a half-perimeter of 0.15 km, and its width is 2/3 of its length. Calculate the area of the playground in square meters and hectares.
Solution Method:
* The problem provides:
- Half perimeter of the rectangle: 0.15 km
- Width: 2/3 of the length
* The problem requires: Calculate the area of the playground in square meters, hectares
* Solution Approach: Transform the problem into finding two numbers when knowing the sum and ratio of the two numbers
- Step 1: Convert the unit from kilometers to meters; draw a line segment diagram (draw the equal parts needed)
- Step 2: According to the diagram above, find the total number of equal parts
- Step 3: Find the width (smaller number) by taking the sum divided by the total number of equal parts, then multiply by the number of parts of the smaller number
- Step 4: Find the length (larger number) by subtracting the width from half the perimeter
- Step 5: Calculate the area of the playground by multiplying the length and width (the result just found above)
- Step 6: Convert the result to square meters, hectares, and conclude.
Answer:
Convert 0.15 km = 150 m
We have the diagram:
According to the diagram, the total number of equal parts is:
2 + 3 = 5 (parts)
The width of the playground is:
150 : 5 x 2 = 60 (m)
The length of the playground is:
150 - 60 = 90 (m)
The area of the playground is:
90 x 60 = 5400(m2)
Convert: 5400m2 = 0.54 ha
Answer: 5400m2 or 0.54 ha.
