Find the area of the composite figure. any angles appearing to be right angles can be considered perpendicular.
i need a clear method used, a accurate individual calculations, and a accurate total area

answer:

99.54 units^2

step-by-step explanation:

you can divide the shape into parts.

i've did it with two rectangles (top and bottom) and a triangle (left)

so the area of the two rectangles is 15(width)x3(height)x2(because there's two of them. so 15x3x2 = 90

to find the area of the triangle you will need to apply some trigonometry to find the height. (i will add it as an image)

so applying that you should get

so you will need to all these up

90 +   = 99.53939 and you approximate to your needs.

answer: ok
