Question

William folds his origami paper along the dotted lines shown below so that the triangular flaps overlap exactly on the square.
If the dimensions of the origami paper are decreased by One-half, what will be the new area of the paper?

Answer 1

5 square inches

20 square inches

25 square inches

10 square inches

Answer 2

the area of origami paper before decrease = 100 square inches
if dimnessions decrease by 1/2 then area decreases by 1/2 ^ 2 = 1/4

so new area = 100 8 1/4 = 25 sq ins

Answer 3

* 100 * 1/4
