Given:
A rectangular piece of cloth (dimensions):
L = length of the rectangle
W = width of the rectangle
The area of the rectangle is:
A = L x W
If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:
A (one sail) = 1/2 (L x W) <span />
P is equal to 29. You take the question backwards: 12*3 then subtract 7
Sequence: 2 + 1 + 1/2 + 1/4 + 1/8 + ...
