if L = 8cm, B=6cm, how to find the length of the diagonal of a rectangle using pythagoras theorem pls?
The sides of rectangle are L = 8 cm B = 6 cm.
Since all angles of rectangle are 90o, then the figure formed by the diagonal and two sides of a rectangle will be a right angle triangle.
The as per Pythagoras theorem :
Hypotenuse2 = Base2 + Perpendicular2
Hypotenuse = √ Base2 + Perpendicular2
Hypotenuse = √62 + 82 = √36 + 64 = √100 = 10 cm.
Ans: 10 cm.
