Answer 1

Answer:

1. The total cost is 4800 and the cost if per s.q m is 12
2. If you divide the total cost by 1 m cost then u will find the area
3. And after that the area is being found
4. Then u will have to find the breadth
5. To find the breadth
6. Area=length ×breadth
7. 400=25 × X
8. 400÷25 =X
9. X=16
10. Perimeter of a rectangle =2(l+b)
11. 2(25+16)
12. 50 +32
13. Perimeter =82m
14. Cost of making a wall =850×82
15. 67700 rs
