Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who
inn [45]

\huge\sf\green{Answer :- }

<h2>Given :- </h2><h2 />
  • Side of the square field = 70m

  • Length of the rectangular field = 90m

  • Breadth of the rectangular field = 60m

<h2>To Find :-</h2>

  • Perimeter of the square field

  • Perimeter of the rectangular field

<h2>Solution :-</h2>

Perimeter of the square = 4 × side

By substituting values,

⇒ 4 × 70m

➥ 280m

<h3><u>Hence, </u><u>Faliha</u><u> runs 280m around a Square </u><u>field</u></h3>

Perimeter of the rectangle = 2( length + Breadth)

By substituting values,

⇒ 2( 90m + 60m )

⇒ 2( 150m)

➥ 300m

<h3><u>Hence, Rameen runs 300m around a rectangular field</u></h3>

By comparing perimeters, Rameen runs more than Faliha

Distance runs more by rameen = Distance covered by rameen - distance covered by faliha

By substituting values,

⇒ 300m - 280m

➠ 20m

<h3><u>Hence, </u><u>Rameen</u><u> runs more around a rectangular field by 20</u><u>m</u></h3>
