One side of a rhombus is 13 cm and one of its diagonal is 24 cm. What is the area of the rhombus?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e 120 cm2
Let p and q be the length of diagonals.
Area = (p × q)/2
And
Side of the rhombus:
a = (p2 + q2)½/2
⇒ q = (4a2 - p2)½ = (4 × 169 - 576)½ = 10
⇒ Area = 24 × 10/2 = 120 cm2
