okay, you're going to want to separate this into a large rectangle and a triangle.
From there you're going to calculate the area of both.
rectangle formula:
A= L*H
Triangle Formula:
A= (L*H)/2
Then you just plug in the numbers and calculate, getting 18 for the rectangle and 16 for the triangle. 18+16 = 34
You add the two areas together as shown above, and then you have your area for the whole shape!
Given that the point B is (1,1) is rotate 90° counterclockwise around the origin.
We need to determine the coordinates of the resulting point B'.
<u>Coordinates of the point B':</u>
The general rule to rotate the point 90° counterclockwise around the origin is given by
The new coordinate can be determined by interchanging the coordinates of x and y and changing the sign of y.
Now, we shall determine the coordinates of the point B' by substituting (1,1) in the general rule.
Thus, we have;
Coordinates of B' =
Thus, the coordinates of the resulting point B' is (-1,1)
