Question

The perimeter of a square having an area 16 cm^{2} will be

• A. 16cm
• B. 8cm
• C. 12cm
• D. 4cm

Answer 1

The correct option is A 16cm

The perimeter of a square of area 16 $c{m}^2$ is ___________________

Solution

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

Therefore Side $\times$ side = 16

Side = 4 cm ( since we have 4 $\times$ 4 = 16; When we look at the factors of 16 ,

16 = 16 $\times$ 1

16 = 8 $\times$ 2

16 = 4 $\times$ 4 ; since the sides have to be equal , it has to be 4 $\times$ 4 = 16)

The perimeter of the square = 4 $\times$ 4 = 16 cm
