Question

A rectangular piece of land measures 850m by 700m.each side is to be fenced with 5 rows of wires.calculate the length of the wire needed and the cost of fencing at rs.80per metre

Answer 1

Step-by-step explanation:

length of wire= 5* perimeter of land

= 5*2(l+b)

= 5*2(850+700)m

= 10(1550)m

= 15500m

cost of fencing= 15500m* Rs 80/m

= Rs 1240000

Answer 2

The length of wire needed for fencing is 15500 m

The cost for fencing is Rs 12,400,00

Step-by-step explanation:

A rectangular piece of land measures 850 m by 700 m

Each side is to be fenced with 5 rows of wires.

First we calculate the perimeter of rectangular land.

Perimeter of rectangular land, P = 2 (L+B)

                                                  P = 2(850+700)

                                                  P = 3100 m

For one row needed 3100 m length of wire.

Total length of wire needed for 5 rows  = 5×3100

                                                                  = 15500 m

Total length of wire needed for fencing is 15500 m

Cost of fencing 1 m of wire = Rs. 80/-

Cost of fencing of 15500 m of wire = 80×15500

                                                          = Rs 1240000

Total cost for fencing is Rs 1240000
