A) 66 ft
B) 100 ft
C) 20 ft
D) 90 ft

Answer 1

Hint
Gunter chain is a geodetic device used for measurement. It had 100 links each 7.92 inches long connected with brass metal rings. It was 66ft in total.

Complete step-by-step answer
Gunter’s chain is a device used for measurement. It is used to measure horizontal distances. It was named after Edmund Gunter who invented it in 1620.

This chain is 66 ft long equal to 20.1 meters. It has 100 links which are marked into groups of ten. They are linked with the help of brass metal rings. Each link is 201 mm long. One fourth of this chain measures 16 feet 6 inches which is equal to 5.03 meters. They were divided decimally as well.
Hence, the total length is 66 ft and the correct option is (A).

Note
Ten of such chains were measured as furlong and eighty of those chains were measured as statute miles. They were mainly used for commercial purposes, for measuring the area of acres of lands. They were used as square links equal to 62.75 square inches. It was convenient as an area one chain by ten chains was equal to one acre. They were used to survey a field as well.
