Factorization is :
Answer:
To find the left triangle we make the two right triangles equal 1 square, making the area of that 2x2 or 4
Then we take the uppermost triangle on the left and find the area of that which is 2x2 / 2 or 2. Then we find the right uppermost triangle which is 5x 2 /2 or 5. Then we take the rightmost triangle and find that 4x 4 /2 or 8. Then we add the square in the middle which is 3 x 4 or 12.
Add those area 4 + 2 + 5 + 8 + 12. You should get 31.
Hope that helps somewhat. You need to divide the shape into easily usable shapes like squares and triangles.
