Question

The lengths of sides of a square of area 9 cm^{2} will be

• A. 3 cm
• B. 4.5 cm
• C. 2.25 cm
• D. 6 cm

Answer 1

The correct option is A 3 cm

The area of a square is given by side $\times$ side

Therefore Side $\times$ side = 9

Side = 3 cm ( since we have 3 $\times$ 3 = 9; When we look at the factors of 16 ,

9 = 9 $\times$ 1

9 = 3 $\times$ 3 ; since the sides have to be equal , it has to be 5 $\times$ 5 = 25)

The length of the side of the square = 3 cm
