Question

Given the formula 1/2(base)(height), what area can you find? a. area of a parallelogram c. area of a trapezoid b. area of a triangle d. area of a rectangle

Answer 1

Answer: b. Area of a triangle.

Explanation:

a. The formula for calculate the area of a parallelogram is:

`A_(p)=b*h`

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:

`A_(tr)=(1)/(2)(b*h)`

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:

`A_(tp)=(h)/(2)(B+b)`

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:

`A_(r)=l*w`

Where "l" is the lenght and "w" is the width.

Then, with the given formula you can't find the area of a rectangle.
