Answer:
473
Step-by-step explanation:
The square surface area is 121 (11x11)
For the triangles, you do 16x11, which equals 176 and then divide by 2, to get 88. Since there are 4 triangles, I did 88x4 and got 352 and then added 121 to get 473
You have to look at the equation and find a common factor bettween all parts. SO, we see they all have an x, so that is the first thing you can factor out. They also have
2x(5x2 4x -3) C
Step-by-step explanation:
take the length of side ab and multiply it by side cd
