Question

Length of diagonal of rectangle with length 'l' and breadth 'b' √l2+b2 for length=4cm ,breadth=3cm

​

Answer 1

Answer:

$\sqrt{14}$

Step-by-step explanation:

$\sqrt{(4)2 + (3)2}$

$= \sqrt{8 + 6}$

$= \sqrt{14}$

Answer 2

Answer: To find the length of diagnal we need to know the properties of rectangle, so one propertie is that teh diagnoal is conqrenst and bisec each other and divide equally. therefore getting a conquent triangle we use the hypotneus theorem, so c=√a2+b2
= √4²+3²
= 8 + 9
c= 17

therefore the diagonal = 17
