To find the height of the triangle, you can use the formula for the area of a triangle: Area = 0.5 * base * height. Given that the area is 400 and the base is 20, you can plug these values into the formula to solve for the height.

400 = 0.5 * 20 * height 400 = 10 * height height = 400 / 10 height = 40

Therefore, the height of the triangle is 40.

1/2(Base x height) = area. Divide 400 by 20 to get 20, and cut it in half. 10 is the height.
