Lesson 4.2: Area I can: Find the area of a circle, triangle, square, and quadrilaterals using their formulas. Vocabulary: Area Base Height Altitude

Area The amount of space inside an object. The number of square units it takes to completely fill a space.

Area of a Circle *On Friday, we learned how to find the circumference of a circle, or the part shown in black; today we are learning how to find the area, or the red part.

Find the Area You are given the radius, find the area. 15

Find the Area You are given the diameter, find the area. 4

Find the Area 13 6

Base The side of a figure that is perpendicular to the height/altitude.

Height The distance from the top of an object to its base. h b

Altitude Height of an object.

Area of a Triangle Think about this: h b How many triangles are in a rectangle? What is the area of a rectangle? What would the area of ONE triangle be?
