Answer: The area is 12.5 units squared
Step-by-step explanation: The trapezoid shown has the parallel lines (bases a and b) given and the vertical (perpendicular) height also given.
The area of a trapezoid is calculated as ;
Area = [(a + b)/2] x h
Where a is 2.5, b is 7.5 and h is 2.5
Area = [(2.5 + 7.5)/2] x 2.5
Area = [(10)/2] x 2.5
Area = 5 x 2.5
Area = 12.5 units squared
