Edge Length of Pentagon given Area and Inradius Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Edge Length of Pentagon - (Measured in Meter) - The Edge Length of Pentagon is the length of one of the five sides of the Pentagon.
Area of Pentagon - (Measured in Square Meter) - The Area of Pentagon is the amount of two-dimensional space taken up by a 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

Area of Pentagon: 170 Square Meter --> 170 Square Meter No Conversion Required
Inradius of Pentagon: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l_e = (2*A)/(5*r_i) --> (2*170)/(5*7)

Evaluating ... ...

l_e = 9.71428571428571

STEP 3: Convert Result to Output's Unit

9.71428571428571 Meter --> No Conversion Required

FINAL ANSWER

9.71428571428571 ≈ 9.714286 Meter <-- Edge Length 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 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.
