Let's go shape by shape!
The area of a rectangle can be calculated as follows:
[tex]L * W = area[/tex] where L = length and W = width
The area of a trapezoid can be calculated as follows:
[tex] \frac{( b_{1} + b_{2})*H}{2} = area [/tex]
where b1 and b2 = lengths of the base and H = height of the shape
The area of a parallelogram can be calculated as follows:
[tex]B * H = area[/tex] where B = length of the base and H = height of the shape
