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

A=L•W

So if Robert wants a square sandbox with an area of 25 feet

The length will be 5 ft and the width will be 5 ft

Because the forumal a=l•w

l=5 w=5

5•5= 25 which is the exact number of feet Robert wants for his sandbox
