A trapezoid's are is height (called "width" in the diagram) times the median (midpoint base).
a = bh The diagrammed trapezoid has two of the quantities given: a = 22.5 h = 6 So ... 22.5 = b 6 b = 22.5 / 6 = 3.75 Now, using the properties of similar figures, if Vanessa's pool has a width of 24, what is the median base? The area of her pond is the product of the two. I expect that you can finish from there. Ads |
