The figure on the top left is a triangle with base 11 and height 8, for an area of
Immediately below, we have a rectangle with dimensions 11 and 9, for an area of
Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height
Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of
Sum these areas and you'll get the total area
For the first question, it would be D: 
÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by 
or 0.25. For the third question, it would be D. 
. This can be solved by dividing by 3. For the fourth question, the answer would be . This can be found by flipping the 4, which would make it look like , and multiplying it by . For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.
