Question

the length of a regular hexagon playground is 13 cm. if it takes 100 rs. per metre to fence it, then how much does it cost to fence four rounds

Answer 1

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

Answer 2

PROVIDED INFORMATION :-

• the length of a regular hexagon playground is 13 cm. if it takes 100 rs

QUESTION :-

• the length of a regular hexagon playground is 13 cm. if it takes 100 rs. per metre to fence it, then how much does it cost to fence four rounds

TO FIND :-

• how much does it cost to fence four rounds = ?

SOLUTION :-

we have formula of regular

hexagon = 6a

first we have to multiply 13 with

6 we get :

= 13 × 6 = 78

it takes 100 rs. per metre to fence

then, we will multiply 78 with 100

we get :

= 100 × 78

= 7800

cost to fence four rounds

= 7800 × 4

we will multiply 7800 with 4 we get :

= rs 31200
