Answer: b. Area of a triangle.
Step-by-step explanation:
a. The formula for calculate the area of a parallelogram is:
[tex]A_{p}=b*h[/tex]
Where "b" is the base and "h" is the height.
Then, with the given formula you can't find the area of a parallelogram.
b. The formula for calculate the area of a triangle is:
[tex]A_{tr}=\frac{1}{2}(b*h)[/tex]
Where "b" is base and "h" is the height.
Then, with the given formula you can find the area of a triangle.
c. The formula for calculate the area of a trapezoid is:
[tex]A_{tp}=\frac{h}{2}(B+b)[/tex]
Where "B" is the larger base ,"b" is the smaller base and "h" is the height.
Then, with the given formula you can't find the area of a trapezoid.
d. The formula for calculate the area of a rectangle is:
[tex]A_{r}=l*w[/tex]
Where "l" is the lenght and "w" is the width.
Then, with the given formula you can't find the area of a rectangle.
