How can you draw a square with a area of 9 sq cm?

A square has all sides the same lenght. This gives us that the area, A, equals two of the sides multiplied together: A=s*s, or A=s2

The area is given as 9 cm2.

s = (sqrt)9

s=3 cm or s = -3 cm.

Since a length of a square can never be negative, the solution is the positive root of 9 cm2, which is 3 cm.
