S.A. is the outer area of the shape, so:
(6 * 10) * 4 = 240
(6*6) * 2 = 72
240 + 72 = 312 in^2
The answer is -33/28, since The least common denominator for both is 28.
width = 5.5 feet and
length = 8 feet
Step-by-step explanation:
Given:
Let Width = w
then length = 2.5 + w
Area = 44.8 square feet
Required:
Find length and Width
Formula:
![Area = Length * Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width)
Putting values to find length and width
![Area = Length * Width\\44.8=(2.5+w)*w\\44.8=2.5w+w^2\\w^2+2.5w-44.8=0\\Solving\,\,using\,\,quadratic\,\,formula:\\w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\w=\frac{-(2.5)\pm\sqrt{(2.5)^2-4(1)(-44.8)}}{2(1)}\\w=\frac{-2.5\pm\sqrt{6.25+179.2}}{2}\\w=\frac{-2.5\pm\sqrt{185.45}}{2}\\w=\frac{-2.5\pm13.618}{2}\\w=\frac{-2.5+13.618}{2}\,\,and\,\,w=\frac{-2.5-13.618}{2}\\w=5.5\,\,and\,\,w=-8.1](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width%5C%5C44.8%3D%282.5%2Bw%29%2Aw%5C%5C44.8%3D2.5w%2Bw%5E2%5C%5Cw%5E2%2B2.5w-44.8%3D0%5C%5CSolving%5C%2C%5C%2Cusing%5C%2C%5C%2Cquadratic%5C%2C%5C%2Cformula%3A%5C%5Cw%3D%5Cfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%5C%5Cw%3D%5Cfrac%7B-%282.5%29%5Cpm%5Csqrt%7B%282.5%29%5E2-4%281%29%28-44.8%29%7D%7D%7B2%281%29%7D%5C%5Cw%3D%5Cfrac%7B-2.5%5Cpm%5Csqrt%7B6.25%2B179.2%7D%7D%7B2%7D%5C%5Cw%3D%5Cfrac%7B-2.5%5Cpm%5Csqrt%7B185.45%7D%7D%7B2%7D%5C%5Cw%3D%5Cfrac%7B-2.5%5Cpm13.618%7D%7B2%7D%5C%5Cw%3D%5Cfrac%7B-2.5%2B13.618%7D%7B2%7D%5C%2C%5C%2Cand%5C%2C%5C%2Cw%3D%5Cfrac%7B-2.5-13.618%7D%7B2%7D%5C%5Cw%3D5.5%5C%2C%5C%2Cand%5C%2C%5C%2Cw%3D-8.1)
So, value of w = 5.5 and -8.1
Since width can't be negative so,
Width = w = 5.5
Length = 2.5+w = 2.5+5.5 = 8
So, width = 5.5 feet and
length = 8 feet

2/3 cup of oatmeal - 10 granola bars
When the number of cups of oatmeal increases, the number of granola bars also increases.
If you use for example twice as many cups of oatmeal, you'll make twice as many granola bars.
Therefore, the first step is to calculate how many times 20 cups of oatmeal is more than 2/3 cup of oatmeal. To do it, divide 20 by 2/3.
![20 \div \frac{2}{3} = 20 \times \frac{3}{2}=\frac{60}{2}=30](https://tex.z-dn.net/?f=20%20%5Cdiv%20%5Cfrac%7B2%7D%7B3%7D%20%3D%2020%20%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D%3D%5Cfrac%7B60%7D%7B2%7D%3D30)
You have 30 times as many cups of oatmeal, so you'll make 30 times as many granola bars.
![10 \times 30= 300](https://tex.z-dn.net/?f=10%20%5Ctimes%2030%3D%20300)
300 granola bars can be made with 20 cups of oatmeal.
