Area of Pentagon given Edge Length and Inradius Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Pentagon = 5/2*Edge Length of Pentagon*Inradius of Pentagon
A = 5/2*l_e*r_i
This formula uses 3 Variables

Variables Used

Area of Pentagon - (Measured in Square Meter) - The Area of Pentagon is the amount of two-dimensional space taken up by a Pentagon.
Edge Length of Pentagon - (Measured in Meter) - The Edge Length of Pentagon is the length of one of the five sides of the Pentagon.
Inradius of Pentagon - (Measured in Meter) - The Inradius of Pentagon is defined as the radius of the circle which is inscribed inside the Pentagon.

STEP 1: Convert Input(s) to Base Unit

Edge Length of Pentagon: 10 Meter --> 10 Meter No Conversion Required
Inradius of Pentagon: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = 5/2*l_e*r_i --> 5/2*10*7

Evaluating ... ...

A = 175

STEP 3: Convert Result to Output's Unit

175 Square Meter --> No Conversion Required

FINAL ANSWER

175 Square Meter <-- Area of Pentagon

What is Pentagon?

A Pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting. A simple pentagon (5-gon) must have five straight sides that meet to create five vertices but do not intersect with each other. A self-intersecting regular pentagon is called a pentagram.
