Question

A rectangular field whose length is 225 m and breadth is 175m is to be fenced.How many km of wire would be required to fence it 5 times over

Answer 1

Answer:

Step-by-step explanation:

length = 225 m

breadth = 175 m

perimeter of the rectangular field = 2 (l+b)

                                                       = 2 ( 225 + 175)

                                                       =  2 x 400

                                                        = 800 m

one times   =   800 m

five times    =  800 x 5

                   =  4000 m

wire would be required to fence in 5 times = 4000 m

                                                                        = 4000 / 1000

                                                                        = 4 km

Answer 2

Answer:

Step-by-step explanation:

Perimeter = 2(l+b) m

2(225+175) m

2(400)m

800 m

Length of wire required to fence it 5 times = 800*5

= 4000m

=4km
