To find the area of the squares, we can use the formula A = s^2, where s is the length of a side.
Given that s = 7, we can substitute this value into the equation to find the area of one square: A = 7^2 = 49 square inches.
Since there are 10 squares, the total area taken up by the squares would be 10 * 49 = 490 square inches.
To find the remaining space for the presentation, we subtract the area of the squares from the total area of the poster board: 720 - 490 = 230 square inches.
Therefore, Robert will have 230 square inches left for his presentation.
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.(1 point)
