Remarks/Examples
 Example 1: A rectangle of area 360 square yards is ten times as long as it is wide. Find its length and width.
Example 2: Explain the derivation of the formula for the area of a triangle.Example 3: The design below is called the Ohio Star. Assuming that it measures 9 inches by 9 inches, calculate the total area of all the orange patches, the total area of all the yellow patches, and the total area of all the green patches. How much fabric of each color will you need to cover an area that measures 72 inches by 90 inches?

 Question:
Marisol is creating a custom window frame that is in the shape of a regular hexagon. She wants to find the area of the hexagon to determine the amount of glass needed. She measured diagonal d and determined it was 40 inches. A diagram of the window frame is shown below.
Which of the following is closest to the area, in square inches, of the hexagon?
 Difficulty: N/A
 Type: MC: Multiple Choice
 Test Item #: Sample Item 2
 Question:
A package shaped like a rectangular prism needs to be mailed. For this package to be mailed at the standard parcelpost rate, the sum of the length of the longest side and the girth (the perimeter around its other two dimensions) must be less than or equal to 108 inches (in.). Figure 1 shows how to measure the girth of a package.
What is the sum of the length, in inches, of the longest side and the girth of the package shown in Figure 2?
