For 13. just add all the sides.
4 + 21 + 23 + 7 + 9 = 64
For 14. multiply width and height of both shapes then add them together.
1.7 x 5.2 = 3.74 ( rectangle area )
3.0 x 3.0 divided by 2 = 4.5 ( triangle area )
Add the two answers
3.74 + 4.5 = 8.24

Lets see the answer to this question the fraction of the entire load of dirt in each mound is b.1/2 this is how i got my answer you multiply 3*1/6=1/2 so the fraction of the entire load of dirt that was in each mound is 1/2
It looks like C since it was the start on the other side.
28a⁴b: 2 · 2 · 7 · a · a · a · a · b
16ab: 2 · 2 · 2 · 2 · a · b
GCF(28a⁴b, 16ab) = 4ab
The answer is A.
