Question

The cost of cultivating a rectangular field at 35 rupees per square metre is rupres 71400 if the width of field is 40m find its length also find the cost of fencing the field at rupees 50 per metre

Answer 1

Total cost of cultivating = R 71400
Cost per my = R 35
Area = 71400 ÷ 35
= 2040 m²
width = 40 m
length = 2040/40
=51 m
Perimeter = 2 (40+51). R = rupees
=2×91
182 m
cost of fencing per m=R 50
total cost = 50 × 182
R 3640

Answer 2

Answer:

₹3640

Step-by-step explanation:

Total cost of cultivating = R 71400
Cost per my = R 35
Area = 71400 ÷ 35

=51 m
Perimeter = 2 (40+51). R = rupees
=2×91
182 m
cost of fencing per m=R 50
total cost = 50 × 182
R 3640
