Solution

If a triangle and a parallelogram are on the same base and between same parallels, then the ratio of the area of the triangle to the area of parallelogram is 1 : 2.

Explanation:

We know that, if a parallelogram and a triangle are on the same base and between the same parallels, then area of the triangle is half the area of the parallelogram.

i.e., Area of triangle = `1/2` Area of parallelogram

⇒ `"Area of triangle"/"Area of parallelogram " = 1/2`

∴ Area of triangle : Area of parallelogram = 1 : 2
