Answer:
A (90 in^2)
Explanation:
The formula for the area of a triangle is 1/2 * bh. Plug in the values of the base and height to get 1/2 * 45, which is 22.5. Multiply that by the four triangles to get 90
A =90 in^2
The area of the rhombus is found by
A = 1/2 d1 * d2 where d1 and d2 are the diagonal lengths
d1 = 2*6 =12
d2 = 2 *7.5=15
A = 1/2 (12*15)
