Question

am is having triangular land with slides (3√5, 5√5, 4√5)m. He has to fence his land. He asked two different workers to do this work. Worker A said total wire reqiured is 12√5 m and worker B said 60√5 m. Which worker is giving right information? Describe the mathematical concept used to find the correct way to calculate total wire required?

If √5 = 2.236 approximately then, how much Ram has to pay if cost of wire is Rs. 100 per m and total labour charges of fencing are Rs. 1000.

​

Answer 1

Answer:

Step-by-step explanation:

Let us take the sides as x, y, z

where,x = 3√5 m

           y = 5√5 m

           z = 4√5 m

Worker A is correct as we need total wire required for fencing,

Therefore, perimeter is required.

the perimeter of a triangle is - Sum Of All sides

Perimeter = x + y + z

                = 3√5 m + 5√5 m + 4√5 m

                = 12√5 m

Therefore, Total Amount = 12√5 × 100 × 1000

                  = 26.83 × 100 × 1000

                  = ₹2683000
