Question

Timothy has a fenced-in garden in the shape of a rhombus. The length of the longer diagonal is 24 feet, and the length of the shorter diagonal is 18 feet.
What is the length of one side of the fenced-in garden?

12 ft
15 ft
21 ft
108 ft

Answer 1

From the Pythagorean Theorem:

side^2 = (.5 * 24)^2 + (.5 * 18)^2

side^2 = 144 + 81

side = sq root (225)

rhombus side = 15 feet
