Step-by-step explanation:
Lets sort out the areas of the polygons to match the areas with the corresponding polygons.
1. Triangle
The formula of the area of the triangle will be:

where b is the base and h is the height of the given triangle
2. rhombus
The formula of the area of the rhombus will be:

where p and q being the diagonals
3. Parallelogram
The formula of the area of the parallelogram will be:

where b is the base and h is the height
4. square
The formula of the area of the square will be:

where s being the length if any side, as all sides are equal in square
5. trapezoid
The formula of the area of the trapezoid will be:

where h is the height and
and
being the bases.
6. regular polygon
The formula of the area of the regular polygon will be:

where a is the apothem and p is the perimeter.
7. equilateral triangle
The formula of the area of an equilateral will be:

where s is the length of one side of the triangle
