Question

Find the diagonal of rectangle whose length and breadth is 6centimetre and 8 centimetres

Answer 1

Length of the diagonal = $\sqrt{l^{2} + b^{2} }$
                                     = $\sqrt{64 + 36}$
                                     = $\sqrt{100}$
                                     = 10 cm

Answer 2

Rectangle :- 
length = 8 cm
breadth = 6 cm

length of the diagonal =√l² + b²
=. ✓(8)² + (6)²
= ✓64 + 36
=. ✓100 = 10

length of the diagonal = 10 cm
 
 (√)it means square root.
