Answer:
The surface area of the composite figure is
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top
so
Step 1
Find the surface area of the rectangular prism of the bottom
The surface area is equal to
Find the area of the base B
substitute
Step 2
Find the lateral area of the rectangular prism of the top
The lateral area is equal to
substitute
Step 3
Find the surface area of the composite figure
