To find how much space Robert will have left for his presentation, we need to subtract the area of the decorative pattern from the total area of the poster board.
The area of each square is given by A = s^2, where s is the length of a side of the square. In this case, s = 7 inches.
The area of one square is A = 7^2 = 49 square inches.
To find the area of the decorative pattern, we need to multiply the area of one square by the number of squares used: 10 squares in this case.
The area of the decorative pattern is 10 * 49 = 490 square inches.
To find how much space Robert will have left, we subtract the area of the decorative pattern from the total area of the poster board:
720 - 490 = 230 square inches.
Therefore, Robert will have 230 square inches left for his presentation if he uses squares with 7-inch sides.
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 squaros
with 7-inch sides, evaluate 720
- 1042 when A= 7. (1 point)
