Question. 91

What is the area of a square whose side is m cm?

Answer:

m × m sq cm

Detailed Answer with Explanation:

  1. A square has all sides equal. If each side is m cm, then:

    ( ext{side} = m ext{cm})

  2. Formula for the area of a square:

    ( ext{Area} = ext{side} imes ext{side})

  3. Substitute the value of the side:

    ( ext{Area} = m imes m)

  4. Multiply the numbers/symbols:

    (m imes m = m^{2})

  5. Add the correct units (because the side is in cm):

    ( ext{cm} imes ext{cm} = ext{cm}^{2})

  6. Final answer:

    ( ext{Area} = m^{2} ext{cm}^{2})
