Question

Find the Perimeter of a rhombus in which diagonals are 6cm and 8cm. (Hint: Find the side of rhombus by using Pythagoras theorem in one of the four triangles formed by diagonals).

Answer 1

Diagonal 1 = 6 cm

Diagonal 2 = 8cm

Lets find side of rhombus

First divide the rhombus in four triangles

Second take a triangle and use pythagoras theorem to find side

Let the side be X

So X square = Half of diagonal 1 square + Half of diagonal 2 square

 X square = 3 square + 4 square

X square = 9+ 16

X square = 25

X = root under 25

X = 5 cm

So the perimeter of the rhombus will be 4* side

                                        = 4*5

                                        =20 cm

I hope It helped you
