Solving 5th grade math problems on pages 17 and 18 of VBT workbook 2, Practice on calculating area, exercise 101
1. Solving exercise 1 - Exercise book for 5th grade math, workbook 2, page 17
Problem Statement:
A land plot has dimensions as shown in the figure. Calculate the area of the land plot.
Solution Method:
Divide the original figure into smaller rectangles, then calculate the area of those rectangles using the formula: Area = length x width.
The area of the land plot equals the sum of the areas of the small rectangles.
Answer:
Divide the given figure into 2 rectangles as shown in the diagram.
The length of rectangle (1) of the land plot is:
40 plus 30 equals 70 (meters)
The area of rectangle (1) of the land plot is:
40 multiplied by 70 equals 2800 (m2)
The width of rectangle (2) of the land plot is:
60.5 minus 40 equals 20.5 (meters)
The area of rectangle (2) of the land plot is:
40 multiplied by 20.5 equals 820 (m2)
The area of the given land plot is:
2800 plus 820 equals 3620 (m2)
The answer is: 3620 square meters.
2. Solving exercise 2 - Exercise book for 5th grade math, workbook 2, page 18
Problem Statement:
A piece of land has dimensions as shown in the figure. Calculate the area of that land plot.
Solution Method:
Divide the original figure into smaller rectangles, then calculate the area of those rectangles using the formula: Area = length x width.
The area of the land plot equals the sum of the areas of the small rectangles.
Answer:
Divide the given figure into 2 rectangles as shown in the diagram.
The area of rectangle (1) of the land plot is:
50 multiplied by 20.5 equals 1025 (m2)
The area of rectangle (2) of the land plot is:
10 multiplied by 40.5 equals 405 (m2)
The area of the adjacent land plot is:
1025 plus 405 equals 1430 (m2)
The answer is: 1430 square meters.
