a square photo display is made up of 60 rows of 60 photos each. the area of each square photo is 4 square inches. how long is each side of the display board?

each photo is 2x2, so
2*60 = 120

To find the length of each side of the display board, we need to determine the total area of the display board. We can then calculate the length of one side by taking the square root of the total area.
First, let's find the area of one row of photos: Since there are 60 photos in each row and the area of each photo is 4 square inches, the total area of one row is 60 photos multiplied by 4 square inches, which gives us 240 square inches.
Since there are 60 rows, we need to multiply the area of one row (240 square inches) by the number of rows (60 rows) to find the total area of the display board.
Total Area = Area of one row x Number of rows
Total Area = 240 square inches x 60 rows
Total Area = 14,400 square inches
Now that we know the total area of the display board is 14,400 square inches, we can find the length of each side by taking the square root of the total area.
Length of each side = Square root of the total area
Length of each side = √14,400 square inches
Length of each side = 120 inches
Therefore, each side of the display board is 120 inches long.
