Question

If one side of a square notebook measures 20 cm, what is the area of the front cover of the notebook?

Answer 1

Salutations!

We know tat square has equal sides, so we will just multiply 20 twice as in
`S*S` or
`S^2`. Both of them are equal.

Area of the front cover of the notebook =
`s^2`

=
`20*20`

=
`400cm^2`

Hope I helped (:

have a great day!
