The length of the shorter diagonal of a rhombus is 16 centimeters. determine the length of the longer diagonal, to the nearest c
entimeter, if the perimeter of the rhombus is 68 centimeters. a15 centimeters b19 centimeters c30 centimeters d38 centimeters
1 answer:
Answer is C.
Since each side is 68/4 = 17 cm ( the hypotenuse of each right triangle), and half of the shorter diag is 8, then 17^2-8^2 = a^2
225=a^2
15 = a, which is half of the larger dish, so the larger diag is 30cm.
