A rhombus is a parallelogram that has all its sides equal in length. the area for a rhombus is A = B * H or you can also use A = d1 * d2/ 2
so step one find your base and your height.
step two - your height is 4.5 and your base is 5
step three - multiply them together.
step 4 - 5 * 4.5
step five - your answer is 22.5
hope this helps, good luck on the assignment.
