Answer 1

You need to remember how to calculate area of each geometric figure. ;)
Triangle (figure A) - \(A = \frac{ 1 }{ 2 }*h*base\)
Square (figure B) - \(A = a*b\) where a and b are different sides of the figure
Trapezoid (figure C and D) - \(A = \frac{ (a + b)}{ 2 }*h\)

Answer 2

Oh, and for trapezoid a and b are the bases

Answer 3

I'm not following...

Answer 4

I gave you the formulas used to calculate area of each figure. I specified which formula corresponds to which figure.

Answer 5

by the way, figure D is a parallelogram. area is height times base
