Description

This image illustrates a sawtooth composite shape made up of a rectangle and four congruent equilateral triangles. This configuration is often seen in mechanical designs and architectural elements.

To calculate the total area of this composite figure, we would add the area of the rectangle (l * w) to the areas of the four equilateral triangles (A = (√3/4)s² for each). The perimeter would involve summing the lengths of all outer sides, excluding any shared edges.

This image shows an hourglass composite shape made up of two congruent equilateral triangles, next to two congruent circular sectors. This configuration is often used in artistic designs and educational contexts. This design also has a shape that looks somewhat elliptical.

To calculate the total area of this composite figure, we would add the areas of the two equilateral triangles (A = (√3/4)s² for each) to the areas of the two circular sectors (½r²θ for each, where θ is the central angle in radians). The perimeter would involve summing the lengths of all outer sides, excluding any shared edges.
