Solution:
Note that:
- Area of rhombus formula: 1/2 x (Product of the diagonals)
Use the formula to find the area of each rhombus.
- Area of rhombus formula: 1/2 x (Product of the diagonals)
- => Area of rhombus: 1/2 x (3.5 x 5)
- => Area of rhombus: 1/2 x (17.5)
- => Area of rhombus: 1/2 x 17.5
- => Area of rhombus: 8.75 cm²
Correct option is C.
