Mathematics Questions

Six equilateral triangles form a regular hexagon with an area of ( 24a^2 – 18 ) square units. What is an equivalent expression for the hexagon’s area based on the area of a triangle? Options: 1. ( 6(4a^2 – 3) ) 2. ( 6(8a^2 – 9) ) 3. ( 6a(12a – 9) ) 4. ( 6a(18a – 12) )

Short Answer

Equilateral triangles have equal sides and angles measuring 60 degrees, forming the basis for understanding regular hexagons, which consist of six equal sides and angles. The area of a regular hexagon can be calculated through its constituent equilateral triangles, with a formula of 24a¬¨‚â§ – 18 or simplified to 6(4a¬¨‚â§ – 3).

Step-by-Step Solution

Step 1: Understanding Equilateral Triangles

Equilateral triangles are unique triangles where all three sides and angles are equal. Each internal angle measures exactly 60 degrees. This equality ensures that the triangles are symmetrical, making them fundamental in various geometric calculations, including the composition of polygons.

Step 2: Defining a Regular Hexagon

A regular hexagon is a polygon characterized by having six equal sides and six equal angles. The regular hexagon can be visually divided into six equilateral triangles. This arrangement not only provides a way to calculate its area but also gives the hexagon its symmetric properties, essential in geometry.

Step 3: Calculating the Area of the Hexagon

The area of a regular hexagon can be derived from the area of the equilateral triangles it contains. The formula for calculating the area is given by 24a¬¨‚â§ – 18. This can also be expressed in a simplified form as 6(4a¬¨‚â§ – 3), which allows for easier calculations. Understanding this relationship is crucial for solving problems related to regular hexagons.
