A square has sides of 6 centimetres. Enter the number of square centimetres in its area.
Correct answer
36 · Accepted units: square centimetres · cm2
Explanation
A square with sides of 6 cm holds 6 rows of 6 unit squares, so its area is 6 multiplied by 6. Entering 24 gives the distance round its four sides, a plain length rather than a measure of the surface covered.
