Answer:
Pentagon is 8
Square is 12
last question is 36
Explanation:
if we know that circle is 7, subtract that from 27. You now have 20. So take out the circle in the second problem.
Pentagon + Square = 20 .
Pentagon +Pentagon + Sqaure =28. Adding a Pentagon to the third problem makes it go from 20 to 28. Looking at the second problem you know that 8 + Square = 20. Subtract 8 from 20. You now have 12.
Square = 12.
