Identify the surface area of the composite figure.
explain it step-by-step.

128 square meters

Step-by-step explanation:

Surface Area is sum of the area of all the surfaces.

In the bottom portion, There are 5 squares (each 4 * 4 dimension) -- front, back, 2 sides, and bottom.

The area of 5 of these are:

5 * (4 * 4) = 80

In the top portion, there are 4 triangles each with dimensions height = 6 and length = 4, so the area of triangle is 1/2 * length * height. Hence, the area of 4 of these are:

4 * ( 1/2 * length * height = 1/2 * 4 * 6  = 12)

= 4 * 12

= 48

Hence total surface area = 80 + 48 = 128 square meters.

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
