Question

if the length and breadth of a rectangle is 12cm and 5cm respectively find diagonal
​

Answer 1

Solution :-

☑ Given :- length = 12cm and breath = 5cm

☑Diagonal = by pythagoras theorem

$diagonal \: = \sqrt{ {12}^{2} + {5}^{2} } \\ \\ = \sqrt{144 + 25} \\ \\ = \sqrt{169} \\ \\ = 13cm \:$

☑ Therefore, the length of diagonal is 13 cm...

Hope it helps ❤☺

Answer 2

Answer:

l=12cm and w=5cm

$diagonal = \sqrt{ {12}^{2} + 5 {}^{2} } \\ \sqrt{144 + 25} = \sqrt{169} = 13 \\ \\ \\ formula \: used \: d = \sqrt{l {}^{2} + {w}^{2} } \\ l \: is \: lengt \\ w \: is \: width \: or \: breadth$
