The lengths of the diagonals of a rhombus are 48 cm and 20 cm. What is the perimeter of the rhombus?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 104 cm
As we know that the diagonals of the Rhombus bisects each other at right angle
Hence, half of diagonal 1 and diagonal 2 = 48/2 = 24cm and 20/2 = 10 cm
By using pythagoras formula,
242 + 102 = side2
⇒ 576 + 100 = side2
side = 26
Perimeter = 4 x side = 4 x 26 = 104 cm
