Videos, worksheets, stories and songs to help Grade 7 students learn how to find the area of shaded region involving polygons and circles.
Sometimes, you may be required to calculate the area of shaded regions. Usually, we would subtract the area of a smaller inner shape from the area of a larger outer shape in order to find the area of the shaded region. If any of the shapes is a composite shape then we would need to subdivide it into shapes that we have area formulas, for example
Area of Polygonstriangle, square, rectangle, parallelogram, rhombus, kite, trapezoid, regular polygon
