Area of Composite Figures

This topic covers the computation of areas of composite figures by breaking them apart into rectangles, parallelograms, and triangles.

Topic: Area of a Composite Figure

  • Find the areas of composite figures by breaking them into rectangles, parallelograms, or triangles

  • Area of a rectangle = Length x Width

  • Area of a triangle = 1/2 x Base x Height

  • Area of a parallelogram = Base x Height

Topic: Area of a Composite Figure - Using Grid

  • We can find the areas of composite figures by breaking them into rectangles, parallelograms, or triangles

  • Area of a rectangle = Length x Width

  • Total area of a figure = Sum of the areas of individual parts of the figure

  • If a composite figure is put on a grid:
    To find the area, count the squares and multiply by the area of one square
