You multiply the height by the length.
The area of a 12 by 7 grid is 84.
Count the number of little grid-blocks inside the shape.
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.
Multiply the two dimensions to get the area. The calculation will give you 12 square units.
Multiply the two dimensions to get the area. The calculation will give you 42 square centimeters.
answer
A 7-by-9 grid has an area of 63 square units.
The difference between and area and grid reference is that an area reference always has 4 numbers, and a grid reference will always have 6 numbers
The area of a 12 by 7 grid is 84.
Multiply length times width.
The use of Pick's Theorem is to find the area of polygons when they are located on a lattice grid.
To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
The grid is a rectangular pattern of dots or lines that extends over the area you specify as the grid limits. The grid displays dots only when the current visual style is set to 2D.
This is basic geography.. area reference always have 4 numbers, but grid reference have 6 numbers.
I think that you draw a square from that line, and find the area of that square.
you simply count the number of shaded graphs inside the grid.
