Question

The breadth of a rectangular park is of 48 meter.If 3 km long wire is required for fencing it.Find the length of the park

Answer 1

Answer:

Step-by-step explanation:

wire required = 3km

length of wire required in meter = 3*1000 = 3000m

perimeter of rectangle = 2(l+b) = 3000m

                                      = 2(x+48) = 3000m

                                      = 2x + 96 = 3000

                                      = 2x = 3000-96

                                      = 2x =2904

                                      = x = 2904\2

                                      = x = 1452

so, the length of the park is 1452 m or 1.452km .

Answer 2

breadth of rectangular park=48m
perimeter of rectangular park=3km=3000m=2(length+breadth)
=3000/2=length+48
=1500-48=length
1452m=length
