Compute the requested value for the given figure.
Compute the area (A)
S = cm²
In this exercise the question randomly alternates between perimeter and area, and the figure can be a square, rectangle, triangle, or one of the composite figures. First read the prompt to see what you have to compute (perimeter or area), then decide which formula to use.
What does the generator do?
The generator picks a figure at random from all the previous exercises and also randomly decides whether to ask for perimeter or area. Dimensions and units are chosen so that the result is always a whole number.
How to use it
First check whether you should compute perimeter or area. Then identify the figure and pick the right formula. Type the number into the box and press “Check”.
