alleryThe diagonals of a rhombus are 16 cm and 30 cm. The length of each side is
A15 cm
B17 cm
C23 cm
D34 cm
Answer & Solution
Correct answer: B. 17 cm
1. Diagonals of a rhombus bisect each other at right angles.
2. Half-diagonals are 8 and 15; side is the hypotenuse of this right triangle.
3. Side = square root of (64 + 225) = square root of 289 = 17 cm.
