Length of rectangle is 1 unit
<u>Solution:
</u>
Given that
Length of a rectangle is width minus 8 units.
Area of rectangle = 9 square units
Need to calculate the length of rectangle.
Let us assume width of rectangle = x
As Length is width minus 8,
Length of the rectangle = x – 8



As given that area of rectangle = 9 square units

On solving above quadratic equation for x, we get

When 
When
As width cannot be negative, so considering x = 9

Hence, Length of rectangle is 1 unit.
Answer:
The answer is 1.21.
Step-by-step explanation:
The hundredth digit in 1.208 is 0, so you have to look at the number after that to either round 0 up or down. The number after 0 is 8. Since 8 is bigger than 5, you round 0 up by 1.
I hope this was clear!

X is simply a letter
Answer:
4(R + 5 + R + 2) [Option B]
Step-by-step explanation:
<u>GIVEN :-</u>
- Length = R + 5
- Width = R + 2
<u>TO FIND :-</u>
- Perimeter of the rectangle
<u>FORMULAE TO BE USED :-</u>
For a rectangle with length 'l' and width 'w' , its perimeter = 4(l + w)
<u>SOLUTION :-</u>
Perimeter = 
= 
= 
Using trigonometric ratio, the value of x is 63.6°
<h3>Trigonometric Ratio</h3>
This is the ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.
Trigonometric ratio are often coined as SOHCAHTOA
In the given triangle, we need to find the value of x using trigonomtric ratio.
Since we have the value of adjacent and hypothenuse, we definitely need to use cosine
cosθ = adjacent / hypothenuse
adjacent = 4
hypothenuse = 9
Substituting the values into the equation;
cos θ = 4 / 9
cos θ = 0.444
θ = cos⁻¹ 0.4444
θ = 63.6°
