Answer:

Step-by-step explanation:

let the angle be 360/6=60

the area of design= ar of sector-ar of triangle

(as one angle is 60 and two sides of the triangle are equal i.e radii the triangle is a equilateral triangle)

Ф/360*πr^2-√3/4*a^2

28*28(1/6*22/7-√3/4)*6

=77.47*6

=464.82

cost=0.35*464.82

=162.68 Rs
