If P, R, T are the areas of parallelogram, a rhombus and a triangle standing on the same base and between the same parallel lines, then which of the following is true?

$R=P=2T$

Parallelogram and Rhombus:

Both the parallelogram and the rhombus will have the same base and height since they are between the same parallel lines. Therefore, their areas will be the same.

Thus, P = R

Triangle:

The area of the triangle with the same base and height will be half of the area of the parallelogram or the rhombus.

Therefore, T = 1P/2

The correct answer is Option (4) → $R=P=2T$
