- Determine the Perimeter for the pentagon shown in the illustration.
State the answer in feet.
- Determine the height of the pentagon shown in the illustration.
- Determine the Area for the pentagon shown in the illustration.
- The first triangle in the illustration (shown below) has dimensions where the height is h1 = 2'
and the length of the base is b1 = 5', so that its Area is
A1 = 5 ft². A second triangle is formed
such that both dimensions are "doubled" (i.e., h2 = 4' and
b2 = 10' ) as illustrated...
- Find the Area of the second triangle: A2 = _______
- By what factor did the Area change (when both dimensions were doubled)?
- Express the answer from part "b" (above), by completing the following equation:
A2 = ___ × A1
