Question

Find the area of the square when the side is doubled and side is halved

Answer 1

area of square =

${s}^{2}$

when s is doubled

area of square will be

$= {2s}^{2} = 4 {s}^{2}$

4 times of original area

when s is halved

area of square will be

$= { \frac{s}{2} }^{2} = \frac{ {s}^{2} }{4}$

that 1/4th of original area
