Written by Adi Ackerman, Head Teacher
The shaded area between two shapes is the area of the larger shape minus the area of the smaller one. When a figure is scaled by k, its perimeter is multiplied by k and its area by k². There are 10 sheets for 8th grade here, each with an answer key and a worked example. Shaded Area With Circles cuts circles from squares, Scale Changes and Area squares the scale factor, and Find the Scale Factor From Area works backward from an area ratio.
