The line AE creates triangle AED and parallelogram ABCE.
The ratio between the area of triangle AED and the area of parallelogram ABCE is 1:3.
Calculate the ratio between sides DE and EC.
To calculate the ratio between the sides we will use the existing figure:
We calculate the ratio between the sides according to the formula to find the area and then replace the data.
We know that the area of triangle ADE is equal to:
We know that the area of the parallelogram is equal to:
We replace the data in the formula given by the ratio between the areas:
We solve by cross multiplying and obtain the formula:
We open the parentheses accordingly:
We divide both sides by h:
We simplify to h:
Therefore, the ratio between is:
