Find the area of the

a. 80in^2
b. 64 in^2
c. 128 in^2
d. 160 in^2

64 in² (Answer B)

Step-by-step explanation:

Note that this rhombus is made up of a large upper triangle and a large lower triangle.  Each of these two triangles has base 2(8 in) (or 16 in) and height 4 in.

The area-of-a-triangle formula is

A = (1/2)(base)(height), which here is

A = (1/2)(16 in)(4 in) = 32 in².

Now double that, because we have an upper triangle of area 32 in² and a lower triangle of the same area 32 in².  So the total area of the rhombus is 64 in²
