Question

Find the area of a square in metre whose side is 0.5 mm.

Answer 1

2.5×10^-7m^2 is the area of square whose side is 0.5 m

Answer 2

Answer:

The area of a square in meter whose side is 0.5 mm is $0.25*10^{-6} m^{2}$

Step-by-step explanation:

• A square is a polygon with four equal sides

• The area of a square with its side represented by (l) is given by the formula

       $A=l^{2}$

From the question, it is given that

the side of the square is $l=0.5mm$

the unit mm can be converted to m as

$1mm=0.001m$

⇒ the side of the square is $l=0.5*10^{-3}m$

therefore the area of the square

$A=0.5*10^{-3}*0.5*10^{-3} =0.25*10^{-6}m^{2}$
