To do this you have to fill in the equation \(base*height=area\), but you don't know the height, so we'll use \(h\) for height. Plugging in the numbers you gave me, the equation is: \(8*h=30\). To solve this, we need to find \(h\). To find height you do \(\frac{area}{base}\). Doing this, we get \(h\) = 3.75 ft.
Hope this helped!
