Question

The area of a square whose side is 40 cm is :​

Answer 1

Answer:

Side of square= 40cm

Area of square=side^2

=(40)^2

=1600cm^2

Answer 2

Answer:

The area of the square will be $1600 cm ^2$.

Step-by-step explanation:

In context to questions

We have to find the area of the square,  

As per questions  

We have

The side of a square is $40cm$,

Here we have to use the formula of area of a square,

The area is equal to side square,

i.e. ${\text} A = (side)^2$

Substitute the value in the formula of area of a square, we get

${\text} A = (40)^2$

Squaring a number is to multiply the number by itself we get,

${\text} A = 40\times40$

${\text} A = 1600cm^2$

Hence, the area of the square is ${\text} 1600cm^2$.
