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.
It is a grid divided into 100 squares.
In a 4 by 3 grid, there are a total of 20 squares. To calculate this, you can start by counting the individual squares of each size within the grid. There are 12 one-by-one squares, 6 two-by-two squares, and 2 three-by-three squares. Adding these together gives a total of 20 squares in a 4 by 3 grid.
You really should do your own homework - this is a question designed to make you analyse number patterns and devise a method to predict the answer that can be applied to grids of differing size. If we start with a square cut into a 3x3 grid, we can count the nine single (1x1) squares in the grid, the one 3x3 square, and then four 2x2* squares, making a total of 14. Try it out, then work your way up to 6x6 (a 36 square grid) by way of 4x4 and 5x5, looking to see how the grid's dimensions correlate to the number of varying-sized squares that can be counted. As a tip- in a 6x6 grid, you will have one 6x6 square, thirty-six 1x1 squares, and how many 2x2, 3x3, 4x4, and 5x5 squares? *The squares can overlap, obviously.
Count the number of squares across the top of the grid, the count the number of squares down the side of the grid. Then multiply these two numbers If you have a grid of 100 squares by 60 squares then the number of squares in the grid is 100x60 = 6000
On a grid containing 100 squares, 25 percent of the grid would be equivalent to shading in 25 squares.
count squares completely inside the circle count squares partially in the circle but divide those by 2 add both parts above.
It is: 5/20 times 100 = 25% shaded squares
There are 5 squares in a 2 by 2 grid if the large square enclosing all four smaller squares is included in the count.

With great difficulty! One way would be to overlay a grid of evenly spaced squares (of a known area) and count the number of squares, but this can hardly be called accurate!
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.
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.
It is not possible to answer in terms of a grid that cannot be seen, but a normal grid of 2 squares x 2 squares will have 5 squares.
You could count them, or you could look at it, notice that there are 3 rows of 4 squares, and recall that (3 x 4 = 12).
