Question

Find the length of the diaginals of rectangle whose length is 6cm and breadth is 4.5 cm

Answer 1

To find the length of diagonal, we have to apply Pythagoras theorem.

In a rectangle, the length and breadth meet at right angle and the diagonal works as hypotenuse. So we can apply the Pythagoras theorem to find the length of diagonal.

(Refer the attachment to see how)

By Pythagoras theorem,

hypotenuse = √(p² + b²)

Here, hypotenuse = diagonal, p = length and b = breadth

So, diagonal = √(6² + 4.5²)

=> diagonal = √(36 + 20.25)

=> diagonal = √(56.25)

=> diagonal = 7.5cm

Your answer is :- 7.5cm

Hope it helps dear friend ☺️✌️

Answer 2

7.5 is a length of diagonals
I hope this is your correct answer
