Workbench for Area of Rectangles

Workbench for area of rectangles
1. Graph rectangle ABCD with A(2,2) B(6,2) C(2,4) and D(6,4)
Use the polygon tool to connect the 4 vertices. Then, use the area tool underneath the angle dropdown to find the area of the rectangle.
Question 1
What is the area of rectangle ABCD?
2. Use Rectangle ABCD from question 1.
A) Double only the width.[br]B) Double only the length.[br]C) Double both the width and the length.
Question 2
A) How did doubling the width affect the area?[br]B) How did doubling the length affect the area?[br]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).
Graph the rectangle and find the area.
Question 3
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.
Use the graph to find the correct responses.
Question 4
Coordinates for C and D are:
5. Using quadrilaterals only, what is the largest area that you can contain if using fencing that is 24 ft long (24 ft will be the perimeter)?
