Question

Find the distance when an object completes seven and half rounds in a rectangular field of length 15 m and breadth 3.5 m

Answer 1

Answer:

first find perimeter

2(l*b)

2(15*3.5)

2*52.5

105

now multiply it by 7.5

7.5*105

787.5

Answer 2

Explanation:

Given,

length = 15m

breadth = 3.5m

so,

perimeter = 2( l+b )

= 2(15+3.5)

=2×18.5

= 37m.

According to question,

distance for 7 round = 37×7

= 259m

Now,

distance for half round = half of perimeter

= 37/2

=18.5m

So,

total distance = 259m + 18.5m

= 277.5m

Hence, the distance covered in 7 and half round is 277.5m .
