# Area rectangle calculator

The calculator has several features allowing it to make area calculations. It is thus possible to calculate the surface of a rectangle, also known area of a rectangle with the area_rectangle function, but also the surface of a square , or the surface of a circle .

## Calculating the area of a rectangle

The area of a rectangle is the area bounded by his side. The area of a rectangle can be calculated using the formula (L*l) where L represents the length and l the width of a side.

Thus, calculating the area of a rectangle whose the length is 3 and the width is 2 is done by typing the following formula area_rectangle(3;2), after calculation, the result 6 is returned.

## Symbolic calculating the area of a rectangle

It is also possible to make symbolic calculation and to calculate the area of a rectangle whose length is and the width 1+y, by typing the following formula area_rectangle(1+x;1+y), after calculation, the result is returned.

## Games and quizzes on calculating the areas of common geometric figures

To apply the different calculation formulas, several quizzes on the calculation of the area of the square, the rectangle, and the circle are proposed.
