Math Problem Statement

Wei Xiang helps his grandpa trim the bushes in the gardens every week. The total area of Garden A and Garden B is 204 m². What is the area of Garden B?

Solution

Let's analyze the problem based on the image you uploaded.

The problem gives the following information:

  • The total area of Garden A and Garden B is 204 m².
  • Garden A is a rectangle with dimensions 6 m by 16 m.
  • We need to find the area of Garden B.

Step-by-Step Solution:

  1. Find the area of Garden A: The area of a rectangle is calculated by multiplying its length by its width. For Garden A: Area of Garden A=6m×16m=96m2\text{Area of Garden A} = 6 \, \text{m} \times 16 \, \text{m} = 96 \, \text{m}^2

  2. Determine the area of Garden B: The total area of both gardens is 204 m². Therefore, the area of Garden B can be found by subtracting the area of Garden A from the total area: Area of Garden B=204m296m2=108m2\text{Area of Garden B} = 204 \, \text{m}^2 - 96 \, \text{m}^2 = 108 \, \text{m}^2

Thus, the area of Garden B is 108 m².


Would you like further clarification or more details on any part of this solution? Here are 5 related questions to expand your understanding:

  1. How do you calculate the perimeter of Garden B based on its area?
  2. If the width of Garden B is known, how do you determine its length?
  3. What if the total area was larger—how would that affect the calculations?
  4. Can you calculate the cost to maintain Garden B if it costs $2 per square meter?
  5. How would the problem change if Garden A had a different shape?

Tip: When solving area problems, always ensure that the units are consistent to avoid confusion.
