See attached image. I don't quite get your diagram.Could You help me solve this problem:
THE MIDDLES OF A QUADRANGLE ARE CONNECTED. WHAT IS THE RATIO BETWEEN THE AREAS OF THE TWO QUADRANGLES?
*the only thing I know is that the second quadrangle is a parallelogram
What is 'it'? The 1st or the 2nd.It is the figure MFEP
Yes, I think also they are congruent and only 2 of them belong to the quadrilateral, but I don’t understand what is the ratio of areas.(is it possible to be 5:8)See attached image. I don't quite get your diagram.
In my image note the 4 shaded triangles. They appear to be congruent. What do you think? How many of them belong to the second quadrilateral? What's the ratio of areas?
First of all we need to figure out what's going on in your diagram. Which quadrilaterals are we talking about? I made my diagram based on your problem. But your diagram appears to contain another quadrilateral (in red). Please explain.Yes, I think also they are congruent and only 2 of them belong to the quadrilateral, but I don’t understand what is the ratio of areas.(is it possible to be 5:8)

Regarding my diagram: the large quadrilateral is divided into 4 triangles. I picked one of them (shaded), but the same thing can be done with the other 3. We are asked about the ratio of the areas. So, in the shaded triangle there are 2 small triangles that belong to the 2nd quadrilateral. 4 belong to the first. What is the ratio of the areas?
Yes, the ratio is 1:2 in the shaded triangle. But the same reasoning applies to the other 3 triangles. So, if the ratio is 1:2 in each triangle, what's the overall ratio of the 2 areas?My diagram is wrong, but yours is not. Thank You for showing me an accurate diagram of the problem.
I suppose the ratio is 2:4 or 1:2. But is this the ratio of the areas of the 2 quadrilaterals? How should I describe the solution?
If the ratio is 1:2 in each triangle, does this probably mean that the overall ratio of the 2 areas is 2:1 (the sum of the ratios of all triangles).?Yes, the ratio is 1:2 in the shaded triangle.

For a formal solution you should justify each step in my approach. Or use a different approach.
How did 1:2 become 2:1?If the ratio is 1:2 in each triangle, does this probably mean that the overall ratio of the 2 areas is 2:1 (the sum of the ratios of all triangles).?
There are 4 types of small triangles. Assign variables to their areas. Write expressions for the areas of 2 quadrilaterals.No, I don’t understand it
Quadrilateral area = area of 4 shaded triangles + 4 other triangles + 4 diff triangles + 4 more triangles = 4 ( ... )I would prefer to fill in what is missing in what You wrote:
Quadrilateral area = area of 4 shaded triangles + 4 other triangles + 4 diff triangles + 4 more triangles
Parallelogram area = area of 2 shaded triangles + 2 unshaded triangles
Ratio of the Parallelogram area to Quadrilateral area = 2:4= 1/2
4a+4b+4c+4d = 4( ? )I am not sure, but is it a variable?
What is P?Is the answer P
