Solution Steps

00:00 Find DC
00:03 We'll use the formula for calculating the area of a parallelogram
00:06 Side(DC) multiplied by height (AE)
00:19 We'll substitute appropriate values and solve for DC
00:40 And this is the solution to the question

Step-by-Step Solution

The formula for the area of a parallelogram:

Height * The side to which the height descends.

We replace in the formula all the known data, including the area:

5*DC = 70

We divide by 5:

DC = 70/5 = 14

And that's how we reveal the unknown!
