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.

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.
