Answer: The area is 12.5 square units
Step-by-step explanation: First things first, the figure identified in the question is a trapezoid. The dimensions are all given as
a = 7.5
b = 2.5 and
h = 2.5
Where a and b are the bases and h is the vertical height.
The area of a trapezoid is calculated as
Area = ½(a + b) x h
Area = ½(2.5 + 7.5) x 2.5
Area = ½(10) x 2.5
Area = 5 x 2.5
Area = 12.5 square units
