Guide to solving Exercise 3 page 95 Mathematics Grade 5
Solution method:
- Step 1: Calculate the area of the garden plot using the trapezoid area formula
- Step 2: Calculate the area of land for planting papayas by multiplying the area of the garden plot by 30% (or dividing by 100, then multiplying by 30)
- Step 3: Calculate the area of land for planting bananas by multiplying the area of the garden plot by 25% (or dividing by 100, then multiplying by 25)
- Step 4: Calculate the number of papaya trees by dividing the area of land for planting papayas by the area of land required for planting 1 papaya tree
- Step 5: Similarly, calculate the number of banana trees by dividing the area of land for planting bananas by the area of land required for planting 1 papaya tree
- Step 6: To find out how many more banana trees there are compared to papaya trees, subtract the number of papaya trees from the number of banana trees (the results found above).
Answer:
a) The area of the trapezoidal garden is:
(70 + 50) x 40 : 2 = 2400 (cm2)
The area for planting papayas is:
2400 : 100 x 30 = 720 (m2)
The area for planting bananas is:
100 x 25 = 600 (m2)
The number of papaya trees planted is:
720 : 1.5 = 480 (trees)
b) The number of banana trees planted is:
600 : 1 = 600 (trees)
The number of banana trees planted more than papaya trees is:
600 - 480 = 120 (trees)
Answer: a) 480 trees
b) 120 trees.
