Question

Each side of a square land of Hamalogo village is 300 meters in length. This land has to be surrounded by a wall of 3 deci meters of equal height from all around. Calculate and how much does it cost to build a wall at the rate of Rs 5000 on 100 square meters?
​

Answer 1

Answer:

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
