What is the area of a square whose side is m cm?
m × m sq cm
A square has all sides equal. If each side is m cm, then:
( ext{side} = m ext{cm})
Formula for the area of a square:
( ext{Area} = ext{side} imes ext{side})
Substitute the value of the side:
( ext{Area} = m imes m)
Multiply the numbers/symbols:
(m imes m = m^{2})
Add the correct units (because the side is in cm):
( ext{cm} imes ext{cm} = ext{cm}^{2})
Final answer:
( ext{Area} = m^{2} ext{cm}^{2})
