Q. 2 C4.9( 11 Votes )

Solve the following examples.

Find the length a diagonal of a rectangle having sides 11 cm and 60cm.

Answer :


Let ABCD be a rectangle, with


AB = CD = 60 cm


BC = DA = 11 cm


And AC be a diagonal.


As, A = 90°


ADC is a right-angled triangle, By Pythagoras Theorem i.e.


(Hypotenuse)2 = (base)2 + (Perpendicular)2


AC2 = (CD)2 + (DA)2


AC2 = 602 + 112


AC2 = 3600 + 121


AC2 = 3721


AC = 61 cm
