Step-by-step explanation:
It is given that the rungs are decreasing uniformly in length from 45 cm at the bottom to 25 cm at the top. So, the lengths of the rungs from an A.P. with a = 45 cm and l = length of 11th rung = 25 cm. = 385 cm. Hence, the required length of the wood to form these rungs is 3.85 m
