Answer:
The answer for the first square (b part 1) is 7x + 7(4) ≈ 7x + 28. For the second square (b part 2), the answer is 7 x (x + 4).
Step-by-step explanation:
In part B, it first asks you to add the areas of both rectangles, so you add your answers from part A. Then it asks you too multiply by length and width. The width is x + 4 and the length is 7, so it's 7 x (x + 4).
The answer is A because if you do 10*10*10 that would give you 1k and if u multiply that by 2 you get 2k
