Answer:
<u><em>Part A) Area of Parallelogram:</em></u>
Area = 
Area = 3 * 
<u><em>Area = 2 feet²</em></u>
<u><em>Part B)</em></u>
We can decompose the parallelogram into two triangle by drawing a diagonal which will divide the parallelogram into two triangles with equal area
<u><em>Part C)</em></u>
The area of each triangle would be the half of the area of parallelogram.
=> <u><em>Area of each triangle = 2 feet²/2 = 1 feet ²</em></u>
Part A) The area of a parallelogram is base × height.
3 × 2/3 = 6/3 = 2
2 feet squared is the area of the whole parallelogram.
Part B) The diagonal of a parallelogram separates it into two congruent triangles.
The area of each triangle will be:
base × height × 1/2
3 × 2/3 × 1/2 = 6/6 = 1
1 foot squared is the area for each triangle.
