Answer:
The sales price of the PS4 is $532.
Step-by-step explanation:
The system sells for $399 after giving 25% off on a Black Friday on the sales price.
Let the sales price of the PS4 system is $x.
Then after giving 25% discount the price will become
Therefore, 0.75x = 399
⇒ x = 532
Therefore, the sales price of the PS4 is $532. (Answer)
Answer:
The area of the given rectangle is 51
Step-by-step explanation:
First we have to find the coordinates of the vertices of the rectangle.
Then the length and breadth of it using distance formula.
The distance d between points (x₁ , y₁) and (x₂ , y₂) is given by
Finally calculate the area of rectangle using the formula,
Area of rectangle = Length * Breadth
From the given graph, we get the coordinates of the rectangle as
A(2,4) , B(-2,3) , C(1,-9) , D(5,-8)
Breadth, AB =
Length, BC =
Now, Area of rectangle = Length * Breadth = AB * BC = √17 * 3√17 = 3 *17 = 51
∴ The area of the given rectangle is 51
