# What will be the Length of School Ground? If

The ratio of the length of a school ground to its width is 5 : 2,. If the width is 40 m, then the length is

- 200 m
- 100 m
- 50 m
- 80 m

**Answer: (2) 100 m**

**Explanation:-
**According to the question,

Let be the length of a school ground is 5X and width is 2X.

Width = 40 m

Then, 2X = 40

X = 40/2 = 20

Then, the length = 5X = 5 x 20 = 100 m.

Hence, the length is (2) 100 m.
