Best ResponseYou've already chosen the best response.1I know the perimeter is 40 because each side of MNOP is 10

Best ResponseYou've already chosen the best response.1I came to that conclusion because of 6810 right triangle

Best ResponseYou've already chosen the best response.1so why is the area 96 and not 100?

Best ResponseYou've already chosen the best response.1isn't each side of quadrilateral MNOP 10?

Best ResponseYou've already chosen the best response.1I am assuming MN is 10 because of the 345 triangle rule

Best ResponseYou've already chosen the best response.2That's right. Are you given more information?

Best ResponseYou've already chosen the best response.1I assume this quad to be a square

Best ResponseYou've already chosen the best response.1since the area is 96;not 100

Best ResponseYou've already chosen the best response.2I think you're supposed to assume that each side length is 10. However, this does not mean it's a square. For example:dw:1347833088897:dwThis quadrilateral actually has an area of 50. Remember that you need to multiply by the height, and the height may be different than the side length.

Best ResponseYou've already chosen the best response.1and I am talking about quad MNOP

Best ResponseYou've already chosen the best response.2Just bear with me for a second. That was just an example to show that having side lengths of 10, doesn't imply that the area is 100.

Best ResponseYou've already chosen the best response.2What I would do, is assume that all the triangles in your problem are congruent. Thus, you find the area of ABCD, and subtract 4*area of MBN. Does this make more sense?

Best ResponseYou've already chosen the best response.1You find the whole area and subtract the part that interferes with MNOP

Best ResponseYou've already chosen the best response.2Right. Are you getting 96 now?
