Math Problem Statement
Solution
Let's solve the problem step by step.
Part (a): Finding the area of the shape.
The grid in the image shows squares with dimensions of . To find the area of the shape, we can count the number of squares fully or partially inside the shape.
From the image, it appears that:
- Each full square contributes an area of .
- There are 14 full squares shaded.
Thus, the total area of the shape is:
Part (b): Drawing a different shape with the same area.
For this part, the requirement is to draw a different shape with an area of 14 cm². You can achieve this by rearranging the full squares in any configuration that still gives a total of 14 squares.
Would you like help with creating or visualizing this alternate shape?

Here are 5 questions related to this concept:
- How can you find the area of irregular shapes on a grid?
- Can a shape have the same area but a different perimeter?
- What is the difference between area and perimeter?
- How can decomposing shapes help in calculating areas?
- What other methods can you use to calculate the area of irregular shapes?
Tip: When counting areas on a grid, focus on counting whole and partial squares carefully to avoid overestimating or underestimating the area.
