For the first post you need to determine the area of the shape. Split the shape and identify smaller shapes. You can identify a rectangle, a right triangle, and a trapezoid. So you will find the area for each. The rectangle (on the top) has an area of what? How would you find its area?

bill533:

i'm thinking you THE ANSWER was C

563blackghost:

Not quite. *Correction: we split the shape into just a rectangle and a trapezoid.* First we need to find the area of the rectangle. \(\large\bf{Area=l \times w}\) Plug. \(\bf{Area = 8 \times 12 = 96}\) ~~ Now we find the area of a trapezoid. \(\large\bf{Area= \frac{a+b}{2}h}\) Plug. \(\large\bf{Area=\frac{8+21}{2}~10}\) Simplify. \(\large\bf{\frac{8+21}{2}~10~~\rightarrow~~\frac{29}{2}~10~~\rightarrow~~14.5(10)~~\rightarrow~~\color{red}{145}}\) Now we add the two numbers. \(\large\bf{Area=145+96}\) With the area you would divide by `0.75`. \(\large\bf{Max= \frac{145+96}{.75}}\)
