Answer:
![2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)](https://tex.z-dn.net/?f=2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A50%29%2B2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A10%29)
Step-by-step explanation:
The formula for the area of a triangle is ![\frac{1}{2} *b*h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2Ab%2Ah)
The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.
Since there are 2 of each triangles, we get:
![2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)](https://tex.z-dn.net/?f=2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A50%29%2B2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A10%29)
The answer that fits is the first option.
