Question

3. A hockey field is 91 metres 40 cm long and 55 metres wide.
How long is the boundary of the field?
4.

MARK MY ANSWER AS BRAINLIEST PLEASE

Step-by-step explanation:

3. Length of the boundary of a hockey field =

91m + 40cm +55m + 91m 40 cm +55m

= 292 m 80 cm

4.

• The starting and the ending points of the race coincide. Now, since the radius of the outer circle is greater than the radius of the inner circle, the length of the boundary of the outer circle will be greater than the length of the boundary of the inner circle. Hence, Valsamma covers more distance than Usha while taking one round of the circular track. Thus, she loses the race even if she runs faster than Usha.

• Usually circular tracks have different starting point because the radius of the track of the different runner are different.
