Question

Find the two bases of the trapezoid attached.

Answer 1

Note: It is an isosceles trapezoid.

Answer 2

Consider breaking it up into shapes you do know parts of. Also, is the line of 40 in the middle between the top and bottom bases?

Answer 3

Yes it is, can you give me the formula, I know the formula to find the middle part whereas they give you the two bases, but i dont know how to find the two bases when they only give you the middle and the height?

Answer 4

There's really not just a formula for every situation. You could have been given another line from one corner to the other corner. It's all about knowing how to use what you do know to solve for it.

Basically what you have here is a trapezoid, but you can also look at it as though they are two trapezoids each with a height of 10 and a base of 40.

Answer 5

Isn't that just to find the area of one of the two trapezoids?

Answer 6

Play around with several equations in general terms and see if you can figure it out. The problem didn't give any extra information did it?

Answer 7

No, thats all the information there is, can you please just tell me the formula???

Answer 8

Answer 9

Excuse me for being rude, but can you please HELP, I believe proportions won't work in this problem...
