Question

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

Answer 1

We know
1 m = 100 cm

Length of the hockey field = 91 m 40 cm
= 91 × 100 + 40 cm
= 9100 + 40 cm
= 9140 cm
Breadth of the hockey field = 55 m
= 55 × 100 cm
= 5500 cm
Now, length of the boundary = 9140 + 5500 + 9140 + 5500 cm
= 29280 cm
= 29200 cm + 80 cm
= 292 m 80 cm

Thus, the boundary of the field is 292 m 80 cm long.
