What is the surface area of the composite figure shown? A 12 cm squared
B 24 cm squared
C 28 cm squared
D 42 cm squared

24 cm²

Step-by-step explanation:

Area triangle = 1/2(4 x 3) = 1/2(12) = 6

Area small rectangle = 1.5 x 4 = 6

Area large rectangle = 3 x 4 = 12

6 + 12 + 6 = 24

Units = cm²

Surface area = 24 cm²
