Question

City officials are putting a garden around a memorial site as shown below.

Answer 1

Answer:

I only remember how to do part A, so sorry for using up an answer.

Step-by-step explanation:

Part A:

$(3x+5)(4x+7)\\ 12x^2+21x+20x+35\\ 12x^2+41x+35 ft^2$

(I also don't know if this is the form you need it in, but I hope I could help a little.)
