Felix and Edith didn’t multiply by one-half the actual area of the triangle is 2.25 square inches and the area of the trapezoid is 10 square inches option third is correct.
What is a trapezoid?
It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.
Area for the triangle:
A = (1/2)(b×h)
A = (1/2)(3×1.5)
A = (1/2)(4.5)
A = 2.25 square inches
Area for the trapezoid:
A' = (1/2)(a+b)h
A' = (1/2)(4+6)2
A' = (1/2)(20)
A' = 10 square inches
Thus, Felix and Edith didn’t multiply by one-half the actual area of the triangle is 2.25 square inches and the area of the trapezoid is 10 square inches option third is correct.
