Sophia: Finding the Area of Composite Figures: Lesson 4

Perimeter check! Pairs work on finding the areas of semicircles and quarter circles using a relationship with squares. The problems challenge pupils to find areas of composite figures made from rectangles, semicircles, and quarter circles.

In this composite figures worksheet, learners solve twelve short answer problems. Students find the area of figures composed of various polygons given a sketch of the figure with side lengths labeled.

Not all structures take the shape of a polygon. The 21st instructional activity in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of...

To find the whole, add and subtract the pieces. A portion of a massive geometry playlist shows how to approach finding the area of a composite figure. The resource works with a couple different composite shapes to find their areas.

Combine the formulas to arrive at one volume. Using the formulas for different solids, the video introduces finding the volume of composite solids. The portion of an extensive playlist on geometry works a couple of problems, one with an...

This lesson explains how to break composite figures into more simple shapes in order to find its area. It is 2 of 4 in the series titled "Finding the Area of Composite Figures."

Investigate how a variety of shapes can be used to form composite figures using this interactive Learn Alberta math resource. Students will also work on using relevant operations and formulas to figure out the total area of composite...

Given composite figures (combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles), students will be able to determine expressions for the area as well as calculate the area of the figure.

Painting an irregular figure can be tricky if we don't know the exact area. This interactive presentation reveals that irregular figures can be broken into smaller, simple figures that use the area formulas. Go through two examples,...

Trapezoids can be tricky! Break down the process of finding the area of a trapezoid with an engaging math video. Learners explore area formula and shown exactly how to plug in information, solve, and simplify.
