(worth 10 points each i believe.) ( zoom / zoom out if needed to see question. (: )
can someone me with a step by step of this problem ? i'll seriously appreciate it, and you so so so much in
don't answer if you're ! i need actual , don't just take my points. (: you!

I'm trying to help you in a easy way. Just multiply the numbers for part 1. And then add the numbers u multiplied from part 1 all together and you will have your answer for part 2. Lol don't report this because i am not good at multiplying so ye but this is what i would have done.

Step 1:
Wall 1: 9 * 18 = 162 sq ft
Wall 2: (21*9) - (7*6) = 147 sq ft
Wall 3: (18*9) - (7*4) = 134 sq ft
Wall 4: (21*9) - (4*3) = 177 ft (I'm assuming you want to subtract the thing in the middle that looks like a window for wall 4)

Step 2:
Add up all the areas of the 4 walls : 162+147+134+177= 620 sq ft

The answer is 225 miles per 4.5 hours. hope this ; )
