help me please! also help with the formula?

Answer:
I believe it's Area = 120cm^2
Step-by-step explanation:
Answer:
solution,
Given: A rhombus
To find: It's area.
Formula to find the area of rhombus:
[tex] = \frac{1}{2} \times d1 \times d2[/tex]
( half of product of diagonals)
Also, in a rhombus ,the diagonals bisects each other.
So,
D1=5*2=10
D2=12*2=24
Area of rhombus:
[tex] \frac{1}{2} \times d1 \times d2 \\ = \frac{1}{2} \times 10 \times 24 \\ = \frac{240}{2} \\ = 120 \: {cm}^{2} [/tex]
Hope this helps..
Good luck on your assignment..
