In every row we can find 60 squares (60 photos). Area of the square is defined as: A = a 2 where a is the length of the side of the square. In this case we are given A and we have to calculate the length of the side. 4 i n 2 = a 2 a = 4 = 2 in When we have 60 photos in a row, the the total length of the row is: 60 ⋅ 2 in = 120 in If the photo-display is a square, then the length of the second side is also 120 in.
The **length **of each side of the **display board **will be 120 inches.
What is a square?
A **square **is a geometrical figure in which we have four sides each side must be equal and the angle between two **adjacent sides **must be 90 degrees.
Area of **square **= Side²
The **perimeter **of the square = 4× side
Length of **diagonal **of square = √(2) × side
Given,
Area of 1 **square photo **= 4 inches²
Since, area = side²
So,
side² = 4 ⇒ side = 2 inches.
Now,
The display board has 60 photos in **raw **so 2 × 60 = 120 inches.
And 60 photos in **column **because 60 photos in each **raw **so 2 × 60 = 120 inches.
Hence "The **length **of each side of the **display board **will be 120 inches".

Each side of the square photo-display board is 120 inches long. This is calculated based on the total number of photos in each row and the area of each photo. Each photo has a side length of 2 inches, resulting in a total length of 120 inches for each side of the board.
