Answer: Length = 28 feet and width = 9 feet
Step-by-step explanation:
Let x = width of the wall.
Then, Length of the wall = 10+2x
Since , Area of rectangle = length x width
Then, as per given,
![252= (10+2x)x\\\\\Rightarrow\ 252=10x+2x^2\\\\\Rightarrow\ 2x^2+10x-252=0\\\\\Rightarrow\ x^2+5x-126=0\\\\\Rightarrow\ x^2+14x-9x-126=0\\\\\Rightarrow\ (x+14)-9(x+14)=0\\\\\Rightarrow\ (x+14)(x-9)=0\\\\\Rightarrow\ x=-14 \ or \ x= 9](https://tex.z-dn.net/?f=252%3D%20%2810%2B2x%29x%5C%5C%5C%5C%5CRightarrow%5C%20252%3D10x%2B2x%5E2%5C%5C%5C%5C%5CRightarrow%5C%202x%5E2%2B10x-252%3D0%5C%5C%5C%5C%5CRightarrow%5C%20x%5E2%2B5x-126%3D0%5C%5C%5C%5C%5CRightarrow%5C%20x%5E2%2B14x-9x-126%3D0%5C%5C%5C%5C%5CRightarrow%5C%20%28x%2B14%29-9%28x%2B14%29%3D0%5C%5C%5C%5C%5CRightarrow%5C%20%28x%2B14%29%28x-9%29%3D0%5C%5C%5C%5C%5CRightarrow%5C%20x%3D-14%20%5C%20or%20%5C%20x%3D%209)
Since width cannot be negative , so x = 9
So width = 9 feet and length = 10+2(9)=10+18 = 28 feet
Hence, length is 28 feet and width is 9 feet of the wall of the barn.
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5
Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75
So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!
