Perimeter and Area of Regular Hexagon
Here we will discuss about the perimeter and area of a Regular
hexagon and some example problems.
Perimeter (P) = 6 × side = 6a
Area (A) = 6 × (area of the equilateral ∆OPQ)
= 6 × \(\frac{√3}{4}\) a\(^{2}\)
= \(\frac{3√3}{2}\) a\(^{2}\)
If the area of a regular hexagon is 24√3 cm2, find its perimeter.
Solution:
Let the side of a regular hexagon be a.
Then, its area = \(\frac{3√3}{2}\) × (Side)2
= \(\frac{3√3}{2}\) × a2
Therefore, 24√3 cm2 = \(\frac{3√3}{2}\) × a2
⟹ a2 = \(\frac{48√3}{3√3}\) cm2
⟹ a2 = 16
⟹ Therefore, a ⟹ 4 cm.
Therefore, perimeter = 6a = 6 × 4 cm = 24 cm.

Here we will solve different types of problems on finding the area and perimeter of combined figures. 1. Find the area of the shaded region in which PQR is an equilateral triangle of side 7√3 cm. O is the centre of the circle. (Use π = \(\frac{22}{7}\) and √3 = 1.732.)
Here we will discuss about the area and perimeter of a semicircle with some example problems. Area of a semicircle = \(\frac{1}{2}\) πr\(^{2}\) Perimeter of a semicircle = (π + 2)r. Solved example problems on finding the area and perimeter of a semicircle
Here we will discuss about the area of a circular ring along with some example problems. The area of a circular ring bounded by two concentric circle of radii R and r (R > r) = area of the bigger circle – area of the smaller circle = πR^2 - πr^2 = π(R^2 - r^2)
Here we will discuss about the area and circumference (Perimeter) of a circle and some solved example problems. The area (A) of a circle or circular region is given by A = πr^2, where r is the radius and, by definition, π = circumference/diameter = 22/7 (approximately).
Here we will get the ideas how to solve the problems on finding the perimeter and area of irregular figures. The figure PQRSTU is a hexagon. PS is a diagonal and QY, RO, TX and UZ are the respective distances of the points Q, R, T and U from PS. If PS = 600 cm, QY = 140 cm
