Question

The side of a square is 4.5 cm. Area of a square is ​

Answer 1

Answer:

Solution,

length (l)= 4.5cm

Area (A)= ?

We know that,

Area of square (A)= Length×length

or, A = 4.5 cm × 4.5 cm

or, A = 20.25cm square

.:. Area of square is 20.25 cm square.

Answer 2

${ \underline{ \underline{ \frak{ \pmb{Correct\:Question}}}}}$

What is the area of a square with a side of 4.5 cm ?

${ \underline{ \underline{ \frak{ \pmb{Solution}}}}}$

We know that,

Area of a square = a²

= 4.5²

= 20.25² cm
