Question

The earliest known unit of length to be used in a major construction project is the “megalithic yard” used by. Builders of stone-henge in southwestern Britiian about 2600 b.c. If 1 megalithic yard= 2.72 plus minus 0.05 ft, convert this length to inches. (Round to the nearest tenth of an inch.)

Answer 1

1 megalthic yard = 2.722 feet ( this means they multiplied with 2.722 to get to feet)

now we need to convert feet to inches :

1 ft = 12 inches

2.722 ft = x

cross multiply

2.722 x 12 = 1 X

therefore x = 32,664

rounding off to the nearest tenth of an inch is equivalent to 32.6 inches
