Answer:
Step-by-step explanation:
Given :-
The length of a regular hexagon play ground is
13 cm.
It takes Rs.100 per metre to fence it.
To find :-
Total cost to fence it four rounds.
Solution :-
Given that
The length of a regular hexagon play ground (a) = 13 cm.
We know that
A regular hexagon has 6 equal sides.
The perimeter of the regular hexagon
= 6a units
The perimeter of the regular hexagon play ground = 6(13) cm
= 78 cm
We know that
100 cm = 1 m
=> 1 cm = (1/100)m = 0.01 m
The perimeter is 78×0.01 = 0.78 m
The cost of fencing around it per metre
= Rs.100
Total cost of fencing around it per 0.78 m
= 0.78×100
= Rs. 78
Total cost of fencing around it four rounds = 4×78
= Rs. 312
Answer :-
The total cost of fencing the regular hexagon play ground four rounds is
Rs. 312
Used formulae:-
→ A regular hexagon has 6 equal sides.
→The perimeter of the regular hexagon
= 6a units
a = side of the regular hexagon
