# 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

a. 1 : 3

b. 1 : 2

c. 3 : 1

d. 1 : 4

**Solution:**

We know that

Area of triangle = 1/2 Area of parallelogram

So we get

Area of triangle/ Area of parallelogram = 1/2

Ratio will be

Area of triangle: Area of parallelogram = 1: 2

Therefore, the ratio of the area of the triangle to the area of the parallelogram is 1: 2.
