The area of a is half of the base multiplied by the height.
a. square
b. parallelogram
c. trapezoid
d. triangle

Here, Area of Square = a²
Area of parallelogram = a * b
Area of Trapezoid = (a+b)/2 * h
Area of Triangle = bh/2

In question, it says "half of the base" not bases, so most appropriate answer would be: Option D) Triangle

Hope this helps!

No, the number of total molecules on the left side of a balanced equation is not equal to the number of total molecules on the right side of the equation. A molecule is the smallest number of atoms bonded together for a chemical reaction. The total number of atoms must be the same, but not molecules. The reactants and products will bond together in different ways leading to different numbers of reactants and products
