Answer:
520rs and 780 rs
Step-by-step explanation:
tilling and leveling both require area
but first we need l and b
we have l = 35m
b = l-10 = 35-10 = 25m
area = l*b = 35*25 = 260m²
rate of leveling = 2 p/m²
cost = area x rate
= 260 x 2
= Rs520
rate for tilling = 3 p/m²
cost = (again area x rate)
= 260 x 3
= Rs.780
