Math symbols were invented for a reason. They help communicate your intent. Here, it looks like you may intend
... f(x) = a(2^x)
When x=0, this will have the value "a". When x=1, this will have the value a^2. The appropriate selection is
... f(0) = 3 when a = 3
For the first part, since you know that 4^2 in 16, which is your area, then the 2 sides are 4 square yards and 4 square yards. For the second part, you know that all sides on a square are equal so if one side is 4 square yards, then so are all the other sides. As a result, 4 times 4 is 16, your perimeter.
Final Answers: Part 1 - The length of one side is 4 yards.
Part 2 - The perimeter is 16 yards.
The area of the pentagon is 1,453 squared centimeters.
Given information-
The length of the apothem of a regular pentagon is 20 cm.
The measure of the perimeter of a regular pentagon is 145.3 cm.
The length of the apothem of a rectangular pentagon is 20 cm.
The measure of the perimeter of a rectangular pentagon is 145.3 cm.
<h3>Pentagon-</h3>
Pentagon is the closed shaped polygon which has 5 sides. When these 5 sides are equal in length then the pentagon is called teh regular pentagon. When four of the sides of pentagon make a rectangle then the pentagon is called the rectangular pentagon.
<h3>Area of regular pentagon-</h3>
Area of regular pentagon is half of the product of its apothem and perimeter. It can be given as,

Thus the area of the pentagon is 1,453 squared centimeters.
