Question

3. Kanchan runs around a square park of side 90,
and Vinita runs around a rectangular park whor
length is 120 m and breadth is 80 m. Who cover
the longer distance and by how much?​

Answer 1

Answer:

length of square =90 m

perimeter of square =4×side=4×90=360m

length of rectangle =120m

breadth of rectangle =80m

perimeter of rectangle=2(l+b)=2(120+80)=2×200=400m

therefore perimeter of rectangle is more than square by(400-360)=40m

therefore Vinita covers more distance by 40m
