Answer:

A.

Step-by-step explanation:

I see the bottom vertices are (x1, y1) and x2, y1).

I assume the top vertices are (x1, y2) and (x2, y2).

If that is correct, the the lengths of the top side and bottom side are x2 - x1.

The lengths of the left side and right side are y2 - y1.

Since there are two horizontal sides and two vertical sides, the perimeter is:

2(x2 - x1) + 2(y2 - y1)

Answer: Choice A.

larisa86 [58]

Hey there! I'm happy to help!

How many times does 20 go into 48?

48/20=2.4

So, we multiply our amount of flour for 20 cookies by 2.4.

2.25×2.4=5.4

Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.

Have a wonderful day! :D
