Mathematics 20-2 M5 Project

Module 5 Project

 

Part 1
 

You may work with a partner or as a small group on this activity; however, each person must submit his or her own answers as part of the project submission.

 

You can choose to print out 1-cm Dot Paper and draw squares on grid paper, or you can use the Geoboard applet. To draw squares using the applet, drag either or both of the red dots. The area of the square created will be shown inside the square.

 

 

This is a screenshot for Geoboard.

 

Using the applet or grid paper, draw squares that have the areas listed in Table 1. Give the exact length of each side of the square. (20 marks)

 

tip

There are different ways to find the exact area of a tilted square. Measurement is not one of the methods because a measurement is always an approximation.

 

Look at the following diagram for one possible way of finding the exact location of a tilted square.

 

This shows a tilted square created on dot paper. The square has one side as the hypotenuse of the right triangle with the other two sides measuring 2 cm and 3 cm. The length of the sides are calculated to be the square root of 13. The area of the triangle is calculated to be 13 square centimetres.
