A plot of land is in the shape of a right angled isosceles triangle The length of the hypotenuse is 50√2m. The cost of fencing it at Rs 3 per meter will be

The correct option is C more than Rs 500Let each equal side be =athen, √2a=50√2⇒a=50mPerimeter =50+50+50√2=170.71mCost of fencing =Rs.(170.71×3)=Rs.512.13

A plot of land is in the shape of a right angled isosceles triangle The length of the hypotenuse is $50 \sqrt{2} m$ . The cost of fencing it at Rs 3 per meter will be

The correct option is C more than Rs 500
Let each equal side be $= a$
then, $\sqrt{2} a = 50 \sqrt{2} \Rightarrow a = 50 m$
Perimeter $= 50 + 50 + 50 \sqrt{2} = 170.71 m$
Cost of fencing $= R s . (170.71 \times 3) = R s .512 .13$
