Arun needed to measure the area of a cardboard required to create his craft project. The shape he needed is displayed in the figure below. Which of the following could be used by him to determine the area of this flower-shaped figure?
A) Sandpaper
B) Nylon paper
C) Graph paper
D) A paper can't determine the area of a figure.
Solution:The correct option is C) Graph paper
Graph paper is an especially useful tool for measuring the area of irregular shapes, like the flower-shaped figure shown. Each square on the graph paper typically has an area of $1 \text{ cm}^2$. To estimate the area of Arun's craft project, one can count the total number of full squares that the figure covers. Since the shape is irregular, some squares will only be partially covered. These partially filled squares are counted separately, and their contribution is considered by counting half of their number. This method provides a reasonable approximation of the area, though it is not perfectly accurate. Thus, using graph paper is an effective way to get a good estimation of the area for irregular figures.
In the figure below, the shaded regions I and II are respectively:
A) Sector, Arc
B) Segment, Arc
C) Segment, Sector
D) Sector, Segment
