Question :-

The area of square is 2cm² , then what is the area of 20 such squares.

________________________________

Solution :-

_________________________________

First Method :-

Area of square is 2cm²

Use formula :-

$\large{\sf{\boxed{\boxed{Area \: = \: side^{2}}}}}$

_____________________[Put values]

Side² = 2

$\sf{Side \: = \: {\sqrt{2}}}$

⟹ Side = √2 cm

_____________________________

A.T.Q,

$\sf{Area \: of \: 20 \: squares \: = \: 20(Side^{2})}$

⟹ Area of 20 squares = 20(√2)²

⟹ Area of 20 squares = 20(2)

⟹ Area of 20 squares = 40 cm²

___________________________

$\huge{\sf{OR}}$

Second Method :-

____________________________

Area of such 20 squares =

⟹ Area of 1 square * 20

⟹ Area of 20 squares = 20 (2)

⟹ Area of 20 Squares = 40 cm²

_____________________________

Area of such 20 squares is 40 cm²
