## How to Find Pentagon Area Calculator?

A pentagon is defined as a geometrical two-dimensional shape, which has five sides and five angles. The pentagon shape is taken from Greek “Penta” denotes five and “gon” denotes angle and it is a five-sided polygon.

The area of a pentagon is defined as the amount of space enclosed within the boundary of a pentagon.

**Area of Pentagon = 1/4√ (5(5 + 2√5)) s ^{2} = 1.72 s^{2} square units**

where 's' is the length of the side of the pentagon

## Solved Examples on Pentagon Area Calculator

**Example 1:**

Find the area of a pentagon whose length of a side is 5 units.

**Solution:**

Area of pentagon = 1.72 s^{2}

= 1.72 × 5^{2}

= 1.72 × 25

= 43 square units

Therefore, the area of a pentagon is 43 square units.

**Example 2:**

Find the area of a pentagon whose length of a side is 8 units.

**Solution:**

Area of pentagon = 1.72 s^{2}

= 1.72 × 8^{2}

= 1.72 × 64

= 110.08 square units

Therefore, the area of a pentagon is 110.08 square units.

**Example 3:**

Find the area of a pentagon whose length of a side is 11 units.

**Solution:**

Area of pentagon = 1.72 s^{2}

= 1.72 × 11^{2}

= 1.72 × 121

= 208.12 square units

Therefore, the area of a pentagon is 208.12 square units.

Similarly, you can try the calculator to find the pentagon area with the following length of sides given.

1) side = 7 units 2) side = 12 units
