To find the area of one square, we use the formula for the area of a square, A = s^2 where s is the length of each side. In this case, s = 7.
So, the area of one square is 7^2 = 49 square inches.
Since Robert wants to use 10 squares, the total area used by the squares is 10 * 49 = 490 square inches.
Therefore, the remaining space for Robert's presentation is 720 - 490 = 230 square inches.
So, the answer is 230 square inches.
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 - 10s ^ 2 when s = 7 (1 point)
230 square inches
