Answer:
Step-by-step explanation:
The formulas for the areas of a rectangle and a parallelogram are actually the same; both involve length and width.
It may be easier to understand this if you draw a rectangle of width w with a drawing of a parallelogram of width underneath. The parallelogram's ends appear slanted; they are neither vertical nor horizontal. However, so long as you measure the length of the rectangle horizontally, all measurements are equal to each other as well as equal to the length of the rectangle.
Hence the calculated areas will be one and the same.
