Question

He plans to cut another piece of cardboard in the same shape. The length of the sides AB and DC of the new piece of cardboard are tripled, and the length of the side AD is doubled. What is the area of the new cardboard piece?

Answer 1

How is this the same shape as before? This is a trapezium and that was a square?

Answer 2

Could you restate that..? I cant understand

Answer 3

the first sentence says he intends to cut another piece of cardboard in the same shape.

But same shape as what? There is obviously a part 1 to this question.

I do not know the measurements of the previous shape. So when he says he triple AB and DC. i do not know multiply what with 3.

Answer 4

It just says "Mark cuts a piece of cardboard in the shape shown below." The measurements don't matter for this question I suppose.

Answer 5

Yes it matters. The diagram has no numbers. The question also has no numbers.
So how am i going to get the answer? :)

Answer 6

I guess my teacher should go back to college!

Answer 7

i think so... You sure this is the whole question? and this is not like a part of one big question?

Answer 8

No. I can give you the answers. That's all that is there.


six times the area of the original cardboard piece
four times the area of the original cardboard piece
five times the area of the original cardboard piece
three times the area of the original cardboard piece

Answer 9

Omg.. u should have given the options. Now i know how to do.

I thought when it asked what is the area, it meant in numbers.

Answer 10

The answer is 6 times the area of the original cardboard piece.

Because the length is now 3 times more. Width is now 2 times more.

So the area (since it is length x width), you get 3 x 2= 6 times more.

Answer 11

Thank you. I always get paranoid because I feel like its TOO easy and I'm wrong!
