Answer:
The answer is option 3.
Step-by-step explanation:
The area of triangle formula is A = 1/2×base×height. Then substitute the following values into the formula :
[tex]area = \frac{1}{2} \times base \times height[/tex]
Let base = 10,
Let height = 12,
[tex]area = \frac{1}{2} \times 10 \times 12[/tex]
[tex]area = \frac{1}{2} \times 120[/tex]
[tex]area = 60 \: \: {m}^{2} [/tex]
