Answer:
12
Explanation:
B x H x 1/2 = area of a triangle
we can break this figure into 4 different triangles and since we have the length of the chords (dotted lines) in the diamond we can easily solve it.
half of QS is 2 and half of PR is 3
2 x 3 = 6
6 / 2 = 3
since there are four triangles multiply 3 by 4 (3 x 4)
and you get 12.
