Workbench for Area of Rectangles
1. Graph rectangle ABCD with A(2,2) B(6,2) C(2,4) and D(6,4)
What is the area of rectangle ABCD?
2. Use Rectangle ABCD from question 1.
A) How did doubling the width affect the area? B) How did doubling the length affect the area? C) How did doubling both the width and length affect the area?
3. Graph Rectangle ABCD with A(-2,0) B(0,6) C(12,2) and D(10,-4).
What is the area? Explain how to find the area of ABCD.
4. If a rectangle has two vertices at A(2,4) and B(2,-2) and an area of 48 squared units, where are the other two vertices? Hint...there are 2 correct responses.
Coordinates for C and D are:
