Question
In the figure, ABCD is a rectangle and PQRS is a square. Find the area of the shaded portion.
The correct answer is: Area of the shaded portion is 275 cm2
Hint:-
Area of shaded portion = Area of rectangle ABCD - Area of rectangle PQRS
Step-by-step solution:-
we can see from the diagram that the Area of shaded portion can be calculated by-
Step- 1: Finding the area of rectangle ABCD (with length = 20 cm & breadth = 15 cm) and
Step- 2: Subtracting the area of square PQRS (with side = 5 cm) from it.
∴ Area of shaded portion = Area of rectangle ABCD - Area of rectangle PQRS
∴ Area of shaded portion = length × breadth - (side)2
∴ Area of shaded portion = (20 × 15) - 52
∴ Area of shaded portion = 300 - 25
∴ Area of shaded portion = 275 cm2
Final Answer:-
∴ Area of the shaded portion is 275 cm2

The scatterplot above shows the revenue, in millions of dollars, that a company carned over several years and a line of best fit for the data. In Year 4 , the difference between the actual revenue and the predicted revenue is n million dollars, where is a posative integer. What is the value of n ? Round your answer to the nearest whole number. (Disregard the 5 sign when gridding your answer.)
Note:
As we are not certain if the point of the actual revenue is exactly at the midpoint of 50 and 60, so instead of taking the midpoint 55, we can also take it to be 54 or 56.
Then the value of n can be 4 or 6 too.
