Can someone tell me the answer step by step about the surface area please I hope some one can answer me

1.) Find the width and length.
- Width is how wide it is
- Length is how long it is

2.) In this case, the width is 14, while the length is 3.

3.) Multiply those to find your surface area. ( 14 x 3 = 42 )

4.) 42 is your surface area, but AREA is always SQUARED ( small 2 on the top right of the number )

5.) Final answer will also have to be labeled. In this case, it is using in (Inches).

6.) 42 inches squared is your final answer.
