The length and breadth of a rectangular hall are 0.4 m and 30 cm respectively. The distance between two opposite comers of the hall is

A) 34.16m                       

B) 50m

C) 34.16cm                     

D) 50cm

Correct Answer: D

Solution :

Length of the rectangular hall = 0.4 m = 40 cm. Breadth of the rectangular hall = 30 cm. Distance between two opposite corners = \[\frac{77}{2}\] \[c{{m}^{2}}\] \[\frac{25\pi }{3}\] \[\left( a \right)\text{ }A-\left( s \right),B-\left( r \right),C-\left( p \right),D-\left( q \right)\]
