Question

The cost of cultivating a rectangular field at 35 per square meter is 71400. If the width of the field is 40m, find its length. Also find the cost of fencing the field at 50 per meter.

Answer 1

Answer:

Step-by-step explanation:

Given: cost of 1 sqm =35

Cost of whole area = 71400

Width= 40m

Answer: Area = 71400/35

= 2040msq

Area = l x b

2040= l x 40

Therefore l = 2040/40

= 51m

Perimeter = 2x l+b

= 2x 51 + 40

=182m

Therefore cost of fencing = 182 x 50

=910

Hope I'm correct.
