Answer:
Step-by-step explanation:
Each of the small triangles are right, so we can add up all the small triangle's areas to find the total area.
The 4-by-10 triangle: The area is .
The other 4-by-10 triangle has the same side lengths and hence the same area, so the area is .
The 4-by-4 triangle: The area is .
The other 4-by-4 triangle has the same area, .
The total area is .
