Question

II. VIII
3. Harry runs around a square field. Each side of it is of 110 metres. Raymond
runs around a rectangular field. Its length is 120 metres and breadth is 80
metres. Who will run more in three rounds and by how much?​

Answer 1

Answer:

perimeter of square field is equals to 440 metre

perimeter of rectangular is 400 metres

, as the perimeter of square field is more than the perimeter of rectangular field hence the Harry will cover more distance

Answer 2

Answer:

Harry

type of field he runs around-square

length of the side=110m

perimeter=4×side

=4×110m

=440m

3 rounds of the field=440m×3=1320m

Raymond

type of field he runs around-rectangle

length of the field=120m

width of the field=80m

perimeter=2(length+breath)

=2(120+80)

=2×200m=400m

3 rounds of the field=3×400m

=1200m

Thus we find Harry runs more by 120m
