<h3>How to find area of an object?</h3>
The area of an object is the product of the length and width of the objects.
Alex added the dimensions of the grid instead of multiplying them.
7+(3x 1. 4)+5+2+(5x1. 4)
For instance,
- Area of a rectangle = length × width
- Perimeter of a rectangle = 2(length + width)
Therefore, Alex found the perimeter of the figure instead of the area".
