Answer:
area of trapezium: -
formula...
½(sum of parallel sides)×height=area
=>240=½(12+x)×12
=>240=(12+x)×6
=>240=60+6x
=>6x=240-60
=>6x=180
=>x=180/6
=>x=30cm
therefore, the value of x is 30 cm.

An eight-digit grid coordinate gives a precision to the nearest 10 meters
Step-by-step explanation:
Grid coordinates are meant to accurately direct to a specific location, using a map that comes with vertical and horizontal lines of equal spacing and numbers attached to each line to map out a location. The crossing vertical and horizontal lines have unique numbers and form small squares known as grid squares.
The more digits in the coordinate of a point the increase in precision an eight- digit gives a precision to the nearest 10 meters
