Answer:
To find the area of a rhombus, you can use the formula:
Area = d1 * d2 / 2
where d1 and d2 are the lengths of the diagonals of the rhombus. In this case, d1 is AC and d2 is BD.
Plugging in the values from the problem, we have:
Area = 18.4 * 36.6 / 2 = 675.44 / 2 = 337.72
Rounding to the nearest tenth, the area of the rhombus is 337.7 in^2.
