Answer:
Cost Including tax would be $318
Step-by-step explanation:
Given:
Price of laptop = $300
Sales tax = 6% of price
To Find:
Cost with tax = ?
Solution:
Cost with tax = Price of laptop + Value of tax
We have to find the value of tax
Value of tax = 6% of Price
putting the value
Value of tax = 6 % * $300
                      
                      = $18
Now Cost with tax = Price of laptop + Value of tax
Putting in the value
Cost with tax = 300 + 18
                       = $318
So Cost Including tax would be $318
 
        
                    
             
        
        
        
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
Part 1) Find the area
we know that
The area of the shape is equal to the area of a quarter of circle minus the area of an isosceles right triangle
so

we have that the base and the height of triangle is equal to the radius of the circle

substitute

simplify
Factor 36

Part 2) Find the perimeter
The perimeter of the figure is equal to the circumference of a quarter of circle plus the hypotenuse of the right triangle
The circumference of a quarter of circle is equal to

substitute the given values

Applying the Pythagorean Theorem
The hypotenuse of right triangle is equal to 

simplify

Find the perimeter

simplify
Factor 6
