You can't find the exact area of of most shapes with a grid, but you can get a pretty good approximation with the following method:
1) Count the number of squares completely inside the shape. Let's call this number X.
2) Count the number of squares that are partially inside the shape (squares with the shape's outline passing through them). We'll call this number Y.
3) A = X + 0.5Y
The answer is in squares, so you need to know the grid spacing if you want to convert to inches or something. Remember, this isn't exact. The smaller the squares, the better the results.
If you need to be really accurate, try the following:
4) Repeat steps 1 - 3 for a bunch of different grid sizes (e.g. 1", 0.5", 0.25". 0.125", etc.).
5) Graph the results from step 4 as Area vs. Grid Size.
6) Draw an approximate curve through the points you graphed, and estimate the asymptote as Grid Size approaches infinity. Carefully cut out the figure and mass it on a good balance. Cut out a square or rectangle of about the same size as the figure from the same grid paper and carefully mass it on the balance. You can then calculate the mass per grid square or mass per unit area. Divide the mass of the figure by mass per unit area and you have the area.

When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
What are some strategies for finding the area of a figure drawn on a grid?
Count the number of grid squares which are entirely or almost entirely inside the figure = ACount the number of grid squares which are approximately half (or more) inside = B Estimated area = A + B/2.
Why is 6 figure grid reference better than 4 figure grid reference?
A 6-figure grid reference provides a more precise location than a 4-figure grid reference by pinpointing a specific area within a grid square. While a 4-figure reference identifies a general location within a 1 km by 1 km square, a 6-figure reference narrows it down to a 100 m by 100 m area. This increased accuracy is especially useful in navigation, mapping, and emergency situations where exact locations are critical.
What is the difference between a 4 and 6 figure grid reference?
The difference is that the 4 figure grid map is used for roughly the place that is located in the map while a 6 figure grid is used to find the exact location on the map. So when there's a need to find the exact location use the 6 figure grid instead of the 4 figure grid map.(:
Why do you use a six figure grid reference?
We use a six figure grid reference because it is more detailed and it will be better if you want to find the exact position of a place.
How do you find the area of a grid?
You multiply the height by the length.

What is the difference between area and grid reference?
Area refers to a specific region or area on a map, while grid reference is a system of identifying locations on a map using a grid of horizontal and vertical lines. Grid reference provides a more precise way to pinpoint a location compared to just referring to an area.
What is 4 figure grid reference?
A 4-figure grid reference is a way of pinpointing a specific location on a map using a combination of two numbers that correspond to horizontal (east-west) and vertical (north-south) grid lines. The first two digits represent the easting (horizontal) and the last two digits represent the northing (vertical). For example, a grid reference of 1234 indicates a location found in the grid square formed by the intersection of the 12th vertical line and the 34th horizontal line. This method provides a general area but is less precise than longer grid references.
