Answer:
area = 22,272
Step-by-step explanation:
area = length * width
to calculate the width, we need the first segment using the pythagorean theorem
![87^{2} + x^{2} = 145^{2}](https://tex.z-dn.net/?f=87%5E%7B2%7D%20%2B%20x%5E%7B2%7D%20%3D%20145%5E%7B2%7D)
![7569 + x^{2} = 21025](https://tex.z-dn.net/?f=7569%20%2B%20x%5E%7B2%7D%20%20%3D%2021025)
![x^{2} = 13456](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D%2013456)
![x = 116](https://tex.z-dn.net/?f=x%20%3D%20116)
length = 116 + 140 = 256
so
area = 87 * 256 = 22,272

Answer:
13 batches of cookies
Step-by-step explanation:
12 2/3 ÷ 2/3 = 12.6666667, it's 13 because 2/3 as a decimal is .6666666 and .6666667 is more than 2/3. So you add one to the answer.
