The value of

The following formula can be used to calculate a rectangle's area.

We can now enter the provided values into the equation.

The simplest method of multiplying is to multiply these terms according to the order specified by the acronym FOIL, which stands for First Outside Inside Last.

We can now enter the specified value for the area.

The equation is then factored and all terms are moved to one side in order to simplify.

At last, we factor the equation. To put it another way, we try to figure out the two things we multiplied together by doing a reverse-FOIL.
