Answer 1

Correct Question:-

The side of a square field is 65 m. What is the length of the fence required all around it? Find the length of fencing done 3 times around the field?

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Answer:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:

▪︎Side of square field = 65m.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:

▪︎Length of fence required all around it.

▪︎Length of fencing done 3 times of field.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

${\sf{Length\ of\ fence\ required\ all\ around\ it}}$

${\sf{= Perimeter\ of\ square\ field}}$

${\sf{= 4 × Side}}$

${\sf{= 4 × 65}}$

${\sf{= 260 m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\sf{\therefore 260m\ fence\ required\ to\ fence\ the\ square\ field.}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\sf{Length\ of\ fencing\ done\ 3 times\ of\ field}}$

${\sf{= 3 × Perimeter\ of\ square\ field}}$

${\sf{= 3 × 260}}$

${\sf{= 780m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\sf{\therefore780m\ fence\ required\ to\ fence\ the\ 3 times\ field.}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Formula to be remembered:-

▪︎Perimeter of square = 4 × side

▪︎Area of square = side × side

▪︎Perimeter of rectangle = 2 ( l + b)

▪︎Area of rectangle = length × breadth
