The complete question is:
<em>A hole the size of a photograph is cut from a red piece of paper to use in a picture frame.</em>
<em />
<em>On a coordinate plane, 2 squares are shown. The photograph has points (-3, -2), (- 2, 2), (2, 1), and (1, -3). The red paper has points (- 4, 4), (4, 4), (4, -4), and (-4, -4).</em>
<em />
<em>What is the area of the piece of red paper after the hole for the photograph has been cut?</em>
<em />
<h2><em>Solution</em></h2><em />
The area of the piece of redpaper after the hole has been cut is equal to the area of the big square less the area of the small rectangle.
<u>1. Area of the big rectangle</u>
Vertices:
- <em>(- 4, 4) </em>
- <em>(4, 4)</em>
- <em>(4, -4)</em>
- <em>(-4, -4)</em>
<em />
The side length is the distance between two consecutive vertices:
The two points (-4,4) and (4,4) has the same y-coordinate, thus the length is just the absolute value of the difference of the x-coordinates:
The area of this square is
<u>2. Area of the small square</u>
Vertices:
- <em>(-3, -2)</em>
- <em>(- 2, 2) </em>
- <em>(2, 1)</em>
- <em>(1, -3)</em>
<em />
To find the side length use the distance formula for two consecutive points, for instance (2,1) and (-2,2):
The area is:
