). Cost of cultivation at the rate of Rs 50/m2
. Cost of fibered wire at rate of Rs 25/m.
Answers
Step-by-step explanation:
fencing
perimeter of a square is 4a a is the side here side is 20 m so perimeter is 20×4 80m
it has to be fenced 3 rounds so 80×3
240m^2
cost of fibered wire will be 240×25 = 6000 rupees
cultivation we need to find area so area of a square field is s^2 side is 20 so 20^2= 20×20 400m^2
1 sq.m is rupees 50 so 400 will be 400×50= 20000 rupees
Given :-
- Side of square = 20 m.
- Cost of cultivation = Rs.50/m².
- Cost of fiber wire = Rs.25/m.
To Find :-
- Total cost of cultivation and fiber wire. ?
Solution :-
we know that,
- Perimeter of square = 4 * side .
- Area of square = (side)² .
so,
→ Perimeter of square = 4 * 20 = 80 m.
then,
→ Length of fiber wire which was fenced three times = 80 * 3 = 240 m .
therefore,
→ Cost of fiber wire = Rate * Total length of wire = 25 * 240 = Rs.6000 . (Ans.)
also,
→ Area of square = Area of cultivation = (20)² = 400 m².
hence,
→ Cost of cultivation = Rate * Area of cultivation = 50 * 400 = Rs.20000 . (Ans.)
