Ok, to solve this, once again you need to fold this map back up into a 3d shape ( in your head). What you should see is that the little overhanging sides that had no measurement, now have a measurement. They measure up to be the same as the 3m. sides. so to find the area of all the rectangles, you need to multiply the base times height. (b)h I will start from the left of your pic. and work my way to the right...not including the little overhanging ones. The first one should measure out to be 3(15) =45 The second to be 6(15) =90 The third to be 3(15) =45 The fourth to be 6(15) =90 :) So you have these, but now you need to get the little over hangers I call them...lol. The width is 6, same as the rectangle they are attached to. And the picture in your mind should tell you that the height is 3, the same as the width of the skinny rectangles that they attach to in your mind. Soooo now they measure out to be 3(6) =18. and you just multiply this by two because they are the same area, right? So that would be 36. ok. Now add all of the areas of the surfaces 45+90+45+90+36 to get a total surface area of.... *drummel please* 306m^2 this means 306m. to the power of 2 if you didn't know. well, I hope you understand better and I hope I helped! ;)
i would say you need to divide 45 and 3. then subtract 45 and 15. then with those two numbers you need to put the amount from 45 / 3 on the top and the 15-45 on the bottom. you will get the probability.
If you take 50 and multiply it by two, you get 100. But, in order to get the right number, you have to multiply 45 by two as well. 45 x 2 is 90. 90 out of 100 is 90 percent. So 90% is the answer.
