Question

Parveen runs around a square of side 40 m. Navin runs around a rectangle of length 45 m and breadth 40 m. who covers more distance and by how much?​

Answer 1

Step-by-step explanation:

Parveen runs around a square of side 40 m.

$perimeter \: of \: a \: square = 4a \:$

Perimeter = 4(40) = 160 m

Praveen runs 160m.

Navin runs around a rectangle of length 45 m and breadth 40 m.

$perimeter \: of \: rectangle \: = 2(length \: + breadth)$

Perimeter of rectangle = 2 (45+40) = 2 (85) =170

Navin runs 170 m.

Ans= Navin runs more distance than Praveen by 10m.

Answer 2

Answer:

Parveen runs around a square of side 40 m.

perimeter \: of \: a \: square = 4a \:perimeterofasquare=4a

Perimeter = 4(40) = 160 m

Praveen runs 160m.

Navin runs around a rectangle of length 45 m and breadth 40 m.

perimeter \: of \: rectangle \: = 2(length \: + breadth)

Perimeter of rectangle = 2 (45+40) = 2 (85) =170

Navin runs 170 m.

Ans= Navin runs more distance than Praveen by 10m.
