If the lengths of the diagonals of a rhombus are 6 cm and 8 cm, the perimeter of the rhombus is:_ explain how?
a. 5 cm. b. 12 cm. c. 20 cm. d.40 cm.
Correct answer is C 20 cm
Rhombus is a paralleogram with all 4 sides equal. since the diagonals paralleogram bisect each other. The diagonals of rhombus bisect each other at 90°.
Hence the Rhombus will be divided in to 4 right angle triangles. with base = 4 cm & Height = 3 cm
using pythgoras theorem you can find the side ( Hyp) will be 5 cm
hence the perimeter of rhombus will be 20 cm
