Question 1. From a rope 15 m long, 4.1⁄3 m is cut off and 3/5 of the remaining is cut off again. Find the length of the remaining part of the rope.
Answer:
Question 2. Perimeter of a rectangle is 2 m less than 2/5 of the perimeter of a square, if the perimeter of the square is 40 m, find the length and breadth of the rectangle given that the breadth is 1/3 of the length.
Answer:
Perimeter of a square = 40 m
Perimeter of a rectangle = 2/5 of 40 – 2 = 16 – 2 = 14 m
Perimeter of a rectangle = 2 (Length + Breadth)
