Question

A farmer wants to put a fence around a piece of land to keep his sheep away from his cows. One side of the fence is 12m, the second side is 11m and the third side is 13m. What is the total perimeter of the fence? The cost of the fence is $ 20.5 per meter. How much will be the total cost of the fence.

Answer 1

Answer:

964.32 $

Step-by-step explanation:

Referring to the image above we can find x =  √122 = 11.04 m

Thus total perimeter of fence = 12+11+13+11.04= 47.04m

Total cost of fence = 20.5 * 47.04 = 964.32 $

Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of perimeter of geometrical figures will help us to solve the question.

Given:

The farmer wanted to put a fence around his land. The sides of the fence are $12m,11m$ and $13m$. The cost of the fence is $\ 20.5$ per meter.

To Find:

We have to find out the total perimeter of the fence and the total cost of this.

Solution:

The one sie of fence is $12m$ , the second side is $11m$and the third side of the fence is $13m$ .

To get the total perimeter, we have to do the sum of the sides of the fence.

Total perimeter is $12+11+13=36m$.

The cose of putting the fence is $\ 20.5$ per $meter$

The cost for $36m$ of fence is $36 \times 20.5= \ 738$

Therefore, the total perimeter of the fence is $36m$ and total cost of putting it is $\ 738$ .
