Question

the length is twice the width of a rectangular. it's area is 2 hectares. find the cost of fencing the field​

Answer 1

Answer:

Answer: width = 50$\sqrt{2}$ meter

lenght = 100$\sqrt{2}$ meter

cost = 2 (  50$\sqrt{2}$ +  100$\sqrt{2}$ ) X cost of fencing per meter

        =300$\sqrt{2}$  x cost of fencing per meter

Step-by-step explanation:

length is twice the width

length = 2W

width =  W

area = length x width

      =  2W X W

        = 2W^2 = 2 hectares

1 hectares = 10000 sq meter

2W = $\sqrt{20000}$

W = 50$\sqrt{2}$ meter =
