Given cap e cap g is equal to 16 and cap f cap h is equal to 12 , what is the length of one side of the rhombus?

The diagonals of a rhombus bisect each other at right angles, so their half-lengths are 16 ÷ 2 = 8 and 12 ÷ 2 = 6. These form the legs of a right triangle whose hypotenuse is one side of the rhombus. Using the Pythagorean theorem, the side length is √(8² + 6²) = √100 = 10 units, so the correct choice is 10 units.
