Find the surface area of a pentagon

So hmm notice the picture below

what you really have is, 2 pentagons and 5 rectangles, stacked up to each other at the edges

so.. .the surface area of the figure, will be, the area of those 5 rectangles added together plus the area of those 2 pentagons

now... notice, each rectangle is a 12x8
now.. to get the pentagons area, keep in mind, the area of a regular polygon is  1/2 * apothem * perimeter

you have the apothem, is given, one side is 12 units long, the perimeter is all sides added together, thus 12+12+12+12+12

so.. get the area of each of the rectangles and those pentagons, sum them up, and that's the surface area of the figure

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
