Question

One side and one diagonal of a rhombus ABCD are 4.5 cm and 5.5 cm respectively.

Answer 1

Answer:

Length of other Diagonal = 7.12 cm

Step-by-step explanation:

Given

Rhombus side = 4.5 cm

Diagonal = 5.5 cm

to find : another diagonal length

Diagonal of rhombus bisect perpendicularly each other

Let say other diagonal = d

=> (5.5/2)² + (d/2)² = 4.5²

=> 5.5² + d² = 9²

=> d² = 50.75

=> d = 7.12 cm

Length of other Diagonal = 7.12 cm
