Find the area and perimeter of a square plot of land whose diagonal is 24 m long.
उत्तर
Area of the square=`1/2xx diagonal^2`
=` 1/2xx24xx24`
Now, let the side of the square be . xm
Thus, we have:
`Area= "side"^2`
⇒ `288=x^2`
⇒`x=12sqrt2`
⇒`x=16.92`
`Permeter=4xx "side"`
=`4xx16.92`
= `67.68m`
Thus, the perimeter of thee square plot is 67.68 . m
