Suppose the lead actor in a play is 5 feet, 9 inches tall. Convert his height to meters. Round your answer to the nearest hundre
Yanka [14]
Given that the lead actor is 5 feet 9 inches tall, converting this to meters we shall have:
1 ft = 0.3048 m
therefore 5 ft will be:

(5/1)×0.3048
=1.524m

next:
1 in = 0.0254 m
therefore 9 inches will be:
(9/1)×0.0254
=0.2286 m

hence; 5 ft 9 inches will be equivalent of:
(1.524+0.2286) m
=1.7526 m
