Question

the diagonal of a rhombus measure 10 cm and 24 cm. Find its perimeter

Answer 1

Hey dear!!

➡Diagonals of the rhombus = 10cm, 24cm

➡Since the diagonals meet at the centre of the rhombus, they create 4 right angles in the centre.

➡So, in this case, we can use the Pythagoras theorem, which states that the sum of the squares on the height and base of a right angle is equal to the square on the hypotenuse.

So, moving on to your solution...

➡Length of the base = 10/2 = 5cm
➡Length of the height = 24/2 = 12cm

By Pythagoras theorem,
➡Hypotenuse = 5^2 + 12^2
➡Hypotenuse = 25 + 144
➡Hypotenuse = 169^2
➡Hypotenuse = 13cm

So, the side of the rhombus is 13cm.

➡Perimeter of the rhombus = 4×side
➡= 4 × 13
➡= 52cm.

Therefore, the perimeter of the rhombus is 52cm.

Hope helped!!
