Using SketchAndCalc’s rectangle drawing tool you can quickly calculate the area of a rectangle or a square by simply drawing it.
Find the area of a perfect square by holding down the shift key and dragging out the square at the size needed. For a rectangle, use the same tool to draw the shapes longest side, then, from the centre of the line, drag outwards to the desired size.
The area of the rectangle will be calculated accurately and displayed in the bottom right corner.
