You can see if the other angles add up to 180 or 360 degrees (depending on shape) then add them to make it the number, for example, if a triangle has a right angle, then the other 2 angles are 45 degrees, knowing that EVERY triangle's angles add up to 180 degrees.

Answer:
312
Step-by-step explanation:
Triangles
1/2 12 *10 = 6*10 = 60

Rectangle
12*16 = 192
Add the two and you have the area 120+192=312
