Surface area of composite 3-D figures practice use the image to answer the question. The image has a big square and a small square hooked to it on the side at the top of the big square is 10 M left side of the big squares 8MM bottom of both squares is 16 and M the right side at the bottom is six and then the side is six and the top right side, 6MM the top right side is 2MM

Answer 1

To find the surface area of the composite figure, we need to calculate the area of each individual shape and then add them together.

Area of the big square:
Side length = 10m
Area = side length * side length = 10m * 10m = 100m^2

Area of the small square:
Side length = 2m
Area = side length * side length = 2m * 2m = 4m^2

Now we need to calculate the area of the rectangle formed by the two squares:
Length = 10m
Width = 2m
Area = length * width = 10m * 2m = 20m^2

Finally, to find the total surface area, we add up the areas of the individual shapes:
Total surface area = 100m^2 (big square) + 4m^2 (small square) + 20m^2 (rectangle) = 124m^2

Therefore, the surface area of the composite figure is 124 square meters.
