Robert is preparing a posterioard presentation. He wants to make a decorative pattern with 10 squares to fill part of the poster. The area of the peter 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
9,940 square inches
34,790 square inches
580 square inches
To find how much space Robert will have left for his presentation, we need to find the area of the squares and subtract it from the total area of the poster.
Since each square has sides of length 7 inches, the area of each square is 7^2 = 49 square inches.
If Robert is using 10 squares, the total area of the squares is 10 * 49 = 490 square inches.
To find the remaining space, we subtract the area of the squares from the total area of the poster: 720 - 490 = 230 square inches.
Therefore, Robert will have 230 square inches left for his presentation. Answer: 230 square inches.
