So now we have the Area of both rectangles and we need to add them together 1575 440

We know the pink rectangle is 22 long by 20 wide so all we have to do is multiply the two numbers. So now we only have to find out the Area of the pink rectangle and add it to the blue rectangle 45 55 22 20 1575 So the Area of the blue rectangle is 45 X 35 which is: 45 55 22 20 1575 We to have find out ? 45 55 22 20 ? So that is 55 - 20 35 - the width of the blue rectangle. The blue rectangle is 45 wide by ? long 45 55 22 20 ? Remember that rectangles have the two opposites sides equal. So we need to find the area of each rectangle 45 55 22 20 This shape is actually 2 rectangles 45 55 22 20 Clearly only the second pair is consistent with the diagram.How to find the Area of this unusual shape 45 55 22 20 Together with $xy=16$ we have two equations we can solve in 2 variables. Note that it is possible to find $x$ and $y$ since triangle ABO is right angled so $4^2=(6-x)^2+y^2$. Let x and y be the horizontal and vertical dimensions of the rectangle formed by the right angle and see the points marked on the image below.Then triangle ABO is similar to triangle BCD. The chord AB subtends the angle 25 at C on the circle, hence it must subtend 50 degrees at the circle centre, D. The answer is 40 degrees since A, B and C lie in a circle centered at D. (Thanks to Smash for pointing out the error in my previous attempt) Hence the total sum is 1080-4x180=360 degrees.

Ignore the 4 reversed triangles then the sum of the interior angles of the octagon that is left is 1080 degrees but each concave angle is equal to the sum of the 2 reversed triangle angles plus 180.
