The area of the rhombus (in cm2) having each side equal to 13 cm and one of its diagonals equal to 24 cm is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 120.
According to the given question,
a2 = p2 + q2
⇒ 132 = 122 + q2
⇒ q2 = 169 - 144
⇒ q2 = 25
⇒ q = 5 cm
Area of rhombus = ½ × 24 × 10 = 120 cm2
