1. The perimeter of rectangle is 200 meter. The breadth is 3/7 part of the length. What is the length?
- A. 30m
- B. 30m
- C. 30m
- D. 30m
Answer: Option D
Explanation:
In case of a rectangle,
2(Length + Width) = perimeter
or, 2(Length + 3/7 of Length) = 200
or, 10/7 of Length = 200/2
So, Length = 200/2 x 7/10 = 70 meter
