lol what is that. delete it
Formula for triangle area = base times height over two. area of smallest triangle: 2*2/2, so 2. area of medium sized triangle: 2*6/2, so 6. the square in between those triangles has an area of four (2*2). the base of the largest triangle is 2+2+6, so 10, and the height is 4. use the formula to find its area is 20. add them all together to get 4+6+4+20 is 34 units^2.
It's impossible for 2 factors of 12 to add up to 16. So there would be no answer to that.
Step-by-step explanation:
A = 80/2 = 40
b = 100/2 = 50
d = 180 - (a+b)
d = 180 - (40+50)
d = 180 - 90
d = 90
