Robert is preparing a poster board presentation he wants to make a decorative pattern with 10 squares to fill part of the poster the area of the poster board is 720 square inches to find how much space Robert will have left for his presentation if he uses squares with 7 inch sides evaluate 720- 10s2 when s = 7
To find the area of each square, we use the formula for the area of a square, which is side length squared. So in this case, each square has an area of 7^2 = 49 square inches.
Since Robert is using 10 squares, the total area of the squares is 10 * (49) = 490 square inches.
To find the amount of space Robert will have left for his presentation, we subtract the total area of the squares from the area of the poster board:
720 - 490 = 230 square inches.
Therefore, Robert will have 230 square inches left for his presentation.
