A rhombus has each side 13 cm and one diagonal 10 cm. Using the right triangle formed by the half-diagonals, find the length of the other diagonal (in cm).

Question

Accepted Answer

24. Half of given diagonal = 5. Side 13 is the hypotenuse: other half = √13^2 - 5^2 = √169-25 = √144 = 12. Full other diagonal = 2 x 12 = 24 cm.
