Question

There is a rectangular park whose length is 20 m and width is 10 m. What is the length of the fence surrounding it?

• A. 30 m
• B. 40 m
• C. 60 m
• D. Can't be determined

Answer 1

The correct option is C

60 m

The length of fence surrounding the park is equal to the perimeter of the rectangular park.
The perimeter can be found as 2 $\times$ (length+breadth)
Perimeter = length of the fence = 2 $\times$ (20 + 10) = 60 m
