This document discusses determining the perimeter and area of various shapes. It provides learning objectives and success criteria for determining the perimeter of shapes when side lengths are given or need to be measured. It then gives examples of calculating the perimeter of swimming pools and other shapes. Formulas for finding the areas of triangles, parallelograms, kites and trapezoids based on the area of a rectangle are also presented, along with examples of area problems.

5. 10.1 Perimeter
How do you determine the perimeter?
Perimeter is the total length around an enclosed area.
For example, we can determine the perimeter of various shapes of swimming pools by finding the
total length of all sides of the swimming pool.
