**drwls**, Monday, July 19, 2010 at 10:37amSince a rhombus has equal sides, the lines AC and BD intersect at right angles, dividing it into four congruent triangles.

The total area is (4)*(1/2)*(4.45)(6.5)

= (1/2)(9)(13) = 58.5

**drwls**, Monday, July 19, 2010 at 11:54amI misread the problem by using 9 for one of the diagonals. The answer should be

A = (1/2)(13)(15) = 97.5

Note that you not have to use the value of AB. Its value, for a true rhombus, should be sqrt[(6.5)^2 + (7.5)^2] = 9.92 , which is close to what was given.
