You have the correct answer. Apply a 180 degree rotation around the point (0,2)
Reason:
We'll connect corners between figures A and B.
Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).
Draw another line from the lower right corner to the upper left corner. This line is in blue.
The red and blue lines intersect at the center of rotation (0,2)
The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.
Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.
Answer:
24 units
Step-by-step explanation:
As we can see in the attached picture. The area will be given by the sum of the area of the rectangle and the area of the triangle in the bottom.
The rectangle has a base of 6 units and a height of 3 units. Therefore:
A1 = bh = 6*3 = 18 units.
The triangle has a base of 6 units and a height of 2 units. Therefore:
A2 = (1/2)bh = (6*2)/ 2 = 6 units
Then, the total area is:
A = A1 + A2 = 6 + 18 = 24 units
The solution to this would be x=2, y=-2
(10 1/2) / (1 3/4) =
10.50 / 1.75 =
6 <== he can make 6 banners
