Answer 2

Let ABCD be the given rectangle. AB

= 11 cm, BC = 60 cm

In ∆ABC, ∠B = 90° [Angle of a rectangle] 

∴ AC2 = AB2 + BC2  [Pythagoras theorem]  = 112 + 602  = 121 +3600  = 3721 

∴ AC = 3721−−−−√3721 [Taking square root of both sides]  = 61 cm  The length of the diagonal of the rectangle is 61 cm.

∴ The length of the diagonal of the rectangle is 61 cm.
