Best ResponseYou've already chosen the best response.3i think i would divide it into two trapezoids. one on top and other on bottom

Best ResponseYou've already chosen the best response.0Any idea how I can figure out the lengths of each side? I'm fairly stumped on that

Best ResponseYou've already chosen the best response.1I agree. Use a horizontal line to divide the figure into two trapezoids. You need to make a few assumptions, if you were not told this info specifically. The bottom right angle must be a right angle. The two side endpoints in the middle of the right and left sides must be at the same height.

Best ResponseYou've already chosen the best response.0How do we know that the two points coming off the right angle are the same height?

Best ResponseYou've already chosen the best response.026015 is 110, so the height of the top trpaezoid is 110. and that means the bottom ones hjeight must be 150.

Best ResponseYou've already chosen the best response.0Then we get 110*195?

Best ResponseYou've already chosen the best response.1@ganeshie8 I don't understand your question. The figure clearly shows that the maximum width of the polygon is 265 ft. How can you move the vertex on the left and make it narrower than 265 ft?

Best ResponseYou've already chosen the best response.3^I agree. and to find area of trapezoid (sum of bases/2) x height so the top would be [(125+265)/2]x 110

Best ResponseYou've already chosen the best response.0THis is what I am putting down for the top, am I correct? We know the top is 110 high (260150), and then we do A=110*((265+125)/2 which adds up to 21450 square feet in the top trapezoid.

Best ResponseYou've already chosen the best response.0Awesome. SO now all we have left is the bottom?

Best ResponseYou've already chosen the best response.0ANd we know the hegiht is 15, the base is 15, and the lid is 265

Best ResponseYou've already chosen the best response.1Read my comment way above. We need to make two assumptions for this problem to be solvable with the info we are given.

Best ResponseYou've already chosen the best response.0Ya, I have to assume 150 for the sides

Best ResponseYou've already chosen the best response.3yes. that is true. now plug those numbers into the formula to find area. also if we dont assume these things, i dont think we have enough info

Best ResponseYou've already chosen the best response.0`The two side endpoints in the middle of the right and left sides must be at the same height.` this assumption is also not required right ?

mathstudent55

Best ResponseYou've already chosen the best response.1If you do not make that assumption, you may not have two trapezoids.

Best ResponseYou've already chosen the best response.0doesn't matter, area wont change

mathstudent55

Best ResponseYou've already chosen the best response.1We also need to assume that the top side and the bottom side are parallel to each other and parallel to the mid segment.

Best ResponseYou've already chosen the best response.1The area won;t change, but how will you calculate it if we do not deal with trapezoids?

Best ResponseYou've already chosen the best response.0@ganeshie8, are you saying I have the wrong question?

mathstudent55

Best ResponseYou've already chosen the best response.1@ganeshie8 Right. BTW, how do you copy a figure into the draw tool, and how do you edit it in color like you did above?

Best ResponseYou've already chosen the best response.0nope, im still trying to convince myself that the actuall question is valid as it stands

Best ResponseYou've already chosen the best response.3the bottom looks right. now just add the two areas together and you have solved your problem based on a lot of assumptions then

Best ResponseYou've already chosen the best response.0Whether or not the question is valid, I gotta write in something. I have 2 days to go before the simester ends and everything closes up, and since I got hit by a car on the 12th last month, I am behind around a week at this point.

Best ResponseYou've already chosen the best response.0To solve this, we cut the top into a trapezoid and the bottom into a trapezoid. We know the top is 110 high (260150), and then we do A=110*((265+125)/2) which adds up to 21450 square feet in the top trapezoid. Bottom trapezoid has a base of 150, a height of 150, and a lid with a length of 265. 31125=150*((265+150)/2) Is this correct? Assuming we made all the agreed on assumptions that have to be done.

nikato

Best ResponseYou've already chosen the best response.3yea. that looks right. but i dont know why you call it a lid, instead of just the other base. and dont forget your last step, to add both the areas
