Robert wants to build a square sandbox that has an area of 25 feet. How long will each side be?
for a square all the sides and angles are the same size (number) Since the area is 25 we only have to figure out one side because every side is the same. Now we have to find out what two of the same numbers equal 25. Like the square root of 25. The answer is 5 because 5 times 5 is 25. each side will be 5ft long
The side of Robert's square sandbox should be 5 ft.
The area of a square is given by the square of the side.
\(\rm{Area\ of\ square = (side)^2\)
Area of the square sandbox = 25 ft²,
The side of Robert's square sandbox
The area of Robert's square sandbox,
Area of the square sandbox = Area of square
\(25\ ft^2 = (side)^2\\\)
Taking square root on both sides,
\(\sqrt{25\ ft^2} = side\\\\side=\sqrt{25\ ft^2}\\side = 5\ ft\)
Hence, the side of Robert's square sandbox should be 5 ft.
