# G.GPE.7 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.
B) Double only the length.
C) Double both the width and the length.

## Question 2

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).

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:
