Answer:
The correct option is B
The area of the composite figure is 34.5 sq. units
Explanation:
The area of the composite figure is the sum of the areas of each shape.
That is:
Area of triangle + Area of square + Area of trapezoid
Area of triangle = 1/2 (base)(height)
= 1/2 (3)(2)
= 3
Area of square = l^2
= 3^2
= 9
Area of trapezoid = 5[4 + (3 + 1 + 1)]/2
= 5(9)/2
= 22.5
Area of figure = 3 + 9 + 22.5
= 34.5
