Answer:
a) The four digit reference of the parking lot = 1632
b) The four digit reference of the power station = 1732
c) The four digit reference of the church = 1630
Explanation:
The National Grid reference is a means of an accurate definition of a location on a given Ordinance Survey map which are maps with lines that divide the area into squares 100 km by 100 km
The eastings are the numbers that go across the map from left to right, while the northings are the numbers that go from the bottom to the top
The four digit number is found by combining the two number code of the abscissa, and ordinate representing the eastings and the northings of the bottom left corner of a square area on the map as follows;
a) The eastings of the parking lot symbol P = 16
The northings of the parking lot = 32
The four digit reference of the parking lot = 1632
b) The eastings of the power station symbol, windmill = 17
The northings of the power station = 32
The four digit reference of the power station = 1732
c) The eastings of the church = 16
The northings of the church = 30
The four digit reference of the church = 1630
