A) 143m

Here's the Surface Area formula I use ⇣

- - - - - - - - - - - - - - - - - - - - - - - - - - -

Surface Area = length x width + length x height + height x width

- - - - - - - - - - - - - - - - - - - - - - - - - - -

So, let's use it...

9m x 7m = 63m

9m x 5m = 45m

5m x 7m = 35m

- - - - - - - - - - - - - - - - - - - - - - - - - - -

63m + 45m + 35m = 143m

Have a great day! :)
