Solving Grade 5 math problems on pages 106, 107, 108 of VBT workbook 2, Practice, exercise 87
1. Solving exercise 1 - Grade 5 math exercise book 2 page 106
Question:
Fill in the blanks with appropriate measurements:
Solution Method
To find the area of a triangle, multiply the base length by the height (using the same unit of measurement) and then divide by 2.
Answer:
2. Solving Exercise 2 - Grade 5 Math Exercise Book 2 Page 107
Question:
Calculate the area of a right triangle (using the formula):
Complete the following:
a)
The area of triangle ABC is: ...........................
b)
The area of triangle DEG is: ...........................
Solution Method
The area of a right triangle equals the product of the lengths of its two legs divided by 2.
Answer:
The area of triangle ABC is:
3 x 4 : 2 = 6 (cm2)
The area of triangle DEG is:
5 x 4 : 2 = 10 (cm2)
3. Solving Exercise 3 - Grade 5 Math Exercise Book 2 Page 108
Question:
Complete the following:
For the parallelogram MNPQ with base PQ= 5cm and height MH=3cm.
The area of triangle MQP is: .................................
The area of triangle MNP is: .................................
Solution Method
- The area of triangle MPP = MH x QP : 2.
- The area of triangle MNP equals the area of triangle MQP because they have equal bases (MN = PQ) and equal heights (the height of the parallelogram MH = 3cm).
Answer:
The area of triangle MQP is:
5 x 3 : 2 = 7.5 (cm2)
The area of triangle MNP equals the area of triangle MQP because they have equal bases (MN = PQ) and equal heights (the height of the parallelogram MH = 3cm).
Therefore, the area of triangle MNP is 7.5 cm2.
Note: The area of triangle MNP can also be calculated by subtracting the area of triangle MQP from the area of parallelogram MNPQ.
