Based on the analysis of the image, the task is to calculate the area of an irregular shape drawn on graph paper. The standard method for solving such a problem involves counting the squares within the shape.
Here is the step-by-step solution:
1.
Identify the Method: The most common and practical way to find the area of an irregular shape on grid paper is to count the number of full squares it covers and then estimate the area of the partial squares along its boundary.
2.
Count Full Squares: A careful examination of the entire shape reveals that there are approximately 45 full squares completely enclosed by the black outline.
3.
Estimate Partial Squares: Along the jagged edges of the shape, there are many partial squares. By visually estimating, these partial squares can be combined to form roughly 20 additional full squares. For example, two half-squares make one full square.
4.
Calculate Total Area: To get the total area, we add the number of full squares to the estimated area from the partial squares.
- Full Squares: 45
- Estimated Partial Squares: 20
- Total Area = 45 + 20 = 65 square units.
Therefore, the estimated area of the irregular shape is
65 square units.
