Question

Construct a square $ABCD$ where $AB=6$ cm and find the perimeter of the square.

• A. $36$ cm
• B. $24$ cm
• C. $26$ cm
• D. None of these

Answer 1

The correct option is B $24$ cm

$\Rightarrow$ We know that all four sides of square are equal angle and all four angles are ${90}^{\circ }$.

$\Rightarrow$ Draw line segment $AB=6cm$

$\Rightarrow$ Construct an angle of ${90}^{\circ }$ at point $A$ and $B$

$\Rightarrow$ Cut of $AD=6cm$ and $BC=6cm$

$\Rightarrow$ Join $CD$

$\Rightarrow$ Thus, $ABCD$ is a required square

$\Rightarrow$ Let $a=6cm$

$\Rightarrow$ Perimeter of square $ABCD=4a=4\times 6=24cm$
