Question

a person runs around a square field of side 70m, while another person runs around a rectangular field with length 90m and breadth 60m. Who covers more distance by how much?

Answer 1

$\huge\underbrace\red{Answer}$

Given :-

• Side of the square field = 70m

• Length of the rectangular field = 90m

• Breadth of the rectangular field = 60m

To Find :-

• Perimeter of the square field

• Perimeter of the rectangular field

Solution :-

Perimeter of the square = 4 × side

By substituting values,

⇒ 4 × 70m

➥ 280m

Hence, A Person runs 280m around a Square field

Perimeter of the rectangle = 2( length + Breadth)

By substituting values,

⇒ 2( 90m + 60m )

⇒ 2( 150m)

➥ 300m

Hence, A Person runs 300m around a rectangular field

Difference between perimeters of fields = Perimeter of Rectangular field - perimeter of square field

By substituting values,

⇒ 300m - 280m

➠ 20m

Hence, The person runs more around a rectangular field by 20m
