Explain how finding the area of a rectangle with whole-number side lengths compares to finding the area

of a rectangle with fractional side lengths.

A = ab and

Step-by-step explanation:

Let the dimensions of a rectangle are all whole numbers, a by b.

Therefore, the area of the rectangle is given by, A = ab.

And, another rectangle with dimensions all fractions say, by .

{The fractions may be a proper or improper fraction}

So, the area of the rectangle for this rectangle will be .

Therefore, in both cases we have to multiply the length and the width of the rectangle to get the area. (Answer)
