Question

mr khetri wants to built a wall around his rectangular plot of land the length of the plot is 500 m and the breadth is 400 m if the costs of building the wall is rs 1000 per meter,how much he will have to spend

Answer 1

l = 500 m
b = 400 m
area = 2(l+b)
         =2(500+400)
         =2*900
         =1800
cost of fencing= Rs 1000/m
cost of fencing around the plot= Rs 1000 * 1800
                                                 = Rs 1800000
