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

Answer 1

Answer:

silky cover more distance than rinky

Step-by-step explanation:

as the perimeter of square = 4 (a)

whereas the perimeter of rectangle= 2(l+b)

therefore the perimeter of square = 4×70 = 240

and rectangle perimeter = 2( 90 + 60 ) = 300

Answer 2

Answer:

Step-by-step explanation

Perimeter of rinky run = 70*4 = 280

Perimeter of silky run = (90+60)*2 =300

Silky run more distance 20m
