Find the area and perimeter of a square plot of land whose diagonal is 24 m long ,. `["take " sqrt(2) = 1.41.]`

Verified by Experts

The correct Answer is:

288 `m^(2), 67.68 m`

Area `=(1)/(2)d^(2)=((1)/(2)xx24xx24)m^(2)=288 m^(2).`
`Now ,a^(2)=288impliesa=sqrt(288)=12sqrt(2) implies 4a =48sqrt(2)m.`
