Answer:
The possible dimensions of the rectangle are (x+6) and( x- 5)
Step-by-step explanation:
The area of the rectangle is given as ![x^{2} + x-30](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%20x-30)
Now, Area of Rectangle = Length x Breadth
So, we need to factorize the given polynomial to find the dimensions of garden.
![x^{2} + x-30 = x^{2} + 6x - 5x - 30](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%20x-30%20%3D%20x%5E%7B2%7D%20%20%2B%206x%20-%205x%20-%2030)
or, ![x^{2} + 6x - 5x - 30 = x(x+6)-5(x+6) = (x+6)(x-5)](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%206x%20-%205x%20-%2030%20%3D%20x%28x%2B6%29-5%28x%2B6%29%20%3D%20%28x%2B6%29%28x-5%29)
or, ![x^{2} + 6x - 5x - 30 = (x+6)(x-5)](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%206x%20-%205x%20-%2030%20%3D%20%28x%2B6%29%28x-5%29)
So, the factors of the given polynomial are (x+6) and( x- 5)
Hence, the possible dimensions of the rectangle are (x+6) and( x- 5)

Answer:
There are 3 different forms of the answer.
Step-by-step explanation:
1. 44/21
2. 2.10
3. 2 2/21
HA + bA = 2
A(h+b) = 2
A = 2/h+b
