Answer: A=70 square units
Step-by-step explanation:
The area of a triangle can be found using the formula [tex]A=\frac{1}{2} bh[/tex]
Let 5=h and 7=b
Plug in the values and solve
[tex]A=\frac{1}{2} (7)(5)[/tex]
[tex]A=17.5[/tex]
However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.
[tex]A=17.5*4[/tex]
[tex]A=70[/tex]
