Solution

Given: A triangle and a parallelogram with the same base and between the same parallels.

To find: The ratio of the area of a triangle and a parallelogram with the same base and between the same parallels.

Calculation: We know that,” the area of a triangle is half the area of a parallelogram with the same base and between the same parallels.”

Hence the ratio of the area of a triangle and a parallelogram with the same base and between the same parallels is  1: 2
