Step-by-step explanation:
We see that the total road to be levelled= horizontal road+vertical road-the common portion to both.
Area of horizontal road= 75×3= 225m
Area of vertical road= 32×3=96m
Area of common portion= 3×3= 9m
total Area :- 225+96= 321m
321-9 = 312m
Rs. 1.80 per metre square
312×1.80= 561.6 Ans
