Watch the teacher solve the problem with clear explanations
00:11 Let's find the height, X.
00:14 To do this, we'll use the area formula for a trapezoid.
00:19 Remember, the entire side equals the sum of its parts.
00:24 That's the sum of the bases, times the height, divided by 2.
00:35 We'll substitute the given values and solve for X. Ready?
00:56 First, divide 20 by 2.
00:59 Next, we'll isolate X on one side of the equation.
01:06 And that's how we solve the problem. Great job!
