Transcript Find Perimeter, Circumference, and Area

Ch. 1.7
In this section we will…
 Review the formulas for area and perimeter for
squares, rectangles, triangles, and circles.
 Use algebra to solve more complex area and perimeter
problems.
What is perimeter?
 The perimeter is the distance around a shape.
 Circumference is the distance around a circle, so
circumference is a specific kind of perimeter.
What is area?
 Area is the amount of space within a given figure.
