The length of the line segment EF will be 55 units. Then the correct option is B.
What is a trapezium?
It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezium, one pair of opposite sides are parallel.
In the diagram, the line segment EF is the given as the half of the sum of the line segment BC and the line segment AD.
EF = (BC + AD) / 2
From the diagram, the length of the line segment AD is 7.6 units and the length of the line segment BC is 3.4 units.
Put these values in equation. Then the length of the line segment EF will be
EF = (3.4+ 7.6) / 2
EF = 11 / 2
EF = 5.5 units
Thus, the length of the line segment EF will be 55 units.
Then the correct option is B.
