<u>Shape #1: A square.</u>
Every side is 4 units long.
The perimeter is 16 units.
The area is <em>16 </em>square units.
<u>Shape #2: A rectangle.</u>
The length is 7.9 units.
The width is 0.1 unit.
The perimeter is 16 units.
The area is <em>0.79</em> of a square unit.
<u>Shape #3: A circle.</u>
The diameter is (16/π) units. (about 5.093 units)
The perimeter (circumference) is 16 units.
The area is (64/π) square units. (about <em>20.37</em> square units)
Your answer is 100ft. This is because to find the radius when you already know the diameter you have to divide the diameter by 2.
The length of the rectangle would be X2 - X1
The height of the rectangle would be Y2-Y1
Perimeter = 2 X length + 2 times height
The perimeter would be 2(X2-X1) + 2(Y2-Y1)
The first choice would be the correct answer.
