Answer:
Length = 15
Width = 6
Area = 90
Step-by-step explanation:
Area of the rectangle = ![{x}^{2} + 3x - 6x - 18](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20-%206x%20-%2018)
Lets factorise the polynomial
![= > x(x + 3) - 6(x + 3)](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20x%28x%20%2B%203%29%20-%206%28x%20%2B%203%29)
![= > (x + 3)(x - 6)](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%28x%20%20%2B%203%29%28x%20-%206%29)
We know that Area = Length × Width
Let the length be (x + 3) & width be (x - 6)
Its given in the question that x = 12. So putting the value of x gives ,
Length = ![x + 3 = 12 + 3 = 15](https://tex.z-dn.net/?f=x%20%2B%203%20%3D%2012%20%2B%203%20%3D%2015)
Width = ![x - 6 = 12 - 6 = 6](https://tex.z-dn.net/?f=x%20-%206%20%3D%2012%20-%206%20%3D%206)
Area = Length × Width = 15 × 6 = 90
Width = x
length = 2x - 3
Perimeter = 2w + 2l
a) 2(x) + 2(2x - 3) = 96 meters
b) 2x + 4x - 6 = 96 meters
6x = 102 meters, x = 17 meters
Since we know x = width
Solution: 17 meters
Answer:
1.75 feet
Step-by-step explanation:
48 ÷ 2 = 14
14 ÷ 2 = 7
7 ÷ 2 = 3.5
3.5 ÷ 2 = 1.75
The answer is concurrent validity.
This kind of validity is based on comparing the results with a measure that has been validated previously.
It is used in more subjective qualities given that they cannot be measured with instruments but it is more an appreciation that depends on the subject that performs the test.
