Question

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

Answer 1

The length of the field = 91 metres 40 cm = 9100 cm + 40 cm

= 9140 cm.

The width of the held = 55 metre = 55 × 100 = 5500 cm

Therefore boundary = length + width + length + width

= 9140 + 5500 + 9140 + 5500

= 29280 cm 

= 29280 ÷ 100 = 292 metre 80 cm
