Question Analysis
The main focus of this question is to compute the area of a regular heptagon. It requires applying the formula for the area of regular polygons, which relies on the apothem and perimeter of the polygon. This tests understanding of geometric concepts related to regular polygon areas.
Key Concept Explanation
The formula for the area of a regular polygon is , where is the apothem (the perpendicular distance from the center of the polygon to the mid - point of a side) and is the perimeter of the polygon. For an sided regular polygon with side length , the perimeter .
Step - by - Step Solution
1. Calculate the perimeter :
A heptagon has sides. Given the side length meters.
Using the formula , we substitute and to get meters.
2. Calculate the area :
Given the apothem meters.
Using the area formula
