63 square units
A 7-by-9 grid has an area of 63 square units.
35
The area of a grid can be calculated by multiplying its length by its width. For a grid that is 7 meters long and 5 meters wide, the area is 7m × 5m = 35 square meters. Therefore, the area of the grid is 35 m².

To determine the types of lines that pass through the given points, we can find their slopes. The slope between points (1, 2) and (9, 9) is (9 - 2) / (9 - 1) = 7/8, while the slope between (0, 12) and (7, 4) is (4 - 12) / (7 - 0) = -8/7. Since the slopes are different, the lines passing through these pairs of points are not parallel and represent two distinct linear equations on the grid.

The area of a 12 by 7 grid is 84.

Whats 7x5? 35. That is your answer.
Total 99 If grid has individual squares 9 high by 11 long, then there will be 99 squares altogether. Same for 11 by 9
A rectangular area 9 units by 7 units has an area of 63 square units.
Well, isn't that just a happy little question! To find the area of a grid, you simply multiply the length by the width. So, for a grid that is 6 cm by 7 cm, you would multiply 6 by 7 to get an area of 42 square centimeters. Just imagine all the wonderful things you could paint on a canvas that size!

9 squares = 18 triangles * * * * * The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
