Question

each side of a square land of our village is 300 meter. we shall fence that square land by 3 dcm, wide wall with the same height around its four sides. let us see that how much will it cost for the wall at the rate of rs. 5000 per 100 sq. meter.​

Answer 1

Cost = Rs 180

Step-by-step explanation:

3 dcm = 3/10 cm  = 3/1000  m

Width of Wall = 3/1000 m

Length of Wall = 4 * 300  = 1200 m

Area = 1200 * 3/1000

= 3.6 m²

100 m² Cost = Rs 5000

=> 1 m² Cost = Rs 5000/100  = Rs 50

=> 3.6 m² Cost = 50 * 3.6 = 180 Rs

Cost = Rs 180
