Answer: The surface area of the composite figure is 127 cm².
Step-by-step explanation:
To find the surface area of the composite figure, we need to break it down into simpler shapes and calculate their areas.
Given dimensions:
- Rectangle: Length = 10 cm, Width = 7 cm
- Square: Side length = 7 cm
- Triangle: Base = 8 cm, Height = 2 cm
Steps to find the surface area:
1. Calculate the area of the rectangle
2. Calculate the area of the square
3. Calculate the area of the triangle
