Question 760737: if the lenght of lenght of rectangle is 56 cm and breadth is 42. find the lenght of each daigonal.
Answer by Lavitesh(3)   (Show Source):
You can put this solution on YOUR website! Length of rectangle = l = 56 cm
Breadth of rectangle = b = 42 cm
Since angle between length and breadth is 90
therefore, By using Pythagoras theorem, we get
56^2 + 42^2 = x^2
3136 + 1764 = x^2
4900 = x^2
Sqrt 4900 = x
70 = x
Also length of diagonal of rectangle is equal
Therefore length of each diagonal is 70 cm
