Class 9 Maths Ganita Manjari Part 2 Chapter 13 Question Answer
Steepness is determined by the slope, calculated as vertical rise divided by horizontal run. For Hill A, slope = 60/70 ≈ 0.857. For Hill B, slope = 60/110 ≈ 0.545. For Hill C, slope = 80/100 = 0.800. Comparing these values shows that Hill B is the least steep, followed by Hill C and Hill A is the steepest. The order is B, C, A.
