If you put four 9-inch square boards together to make a bigger square, what would be the area of the new larger board in square feet?
23 square feet
not an answer choice
276 in
27 square feet
To find the area of the new larger board, we need to determine the length of its sides by adding up the lengths of the smaller square boards.
Each 9-inch square board has sides measuring 9 inches. So, if we put four of these boards together, we will have a larger square board with sides measuring 9 inches + 9 inches + 9 inches + 9 inches = 36 inches.
To convert inches to feet, remember that there are 12 inches in a foot. Therefore, to find the length of the sides of the larger square board in feet, we need to divide 36 inches by 12, giving us 3 feet.
To find the area of a square, we multiply the length of one side by itself. In this case, the sides of the larger square board are 3 feet long, so we multiply 3 feet by 3 feet, which gives us an area of 9 square feet.
Therefore, the area of the new larger board made by putting four 9-inch square boards together would be 9 square feet.
