Width is x.

Length is (x + 1).

Area = length*width

56 = x(x+1)

x² + x - 56 = 0

(x+8)(x-7)=0

x = - 8, or x = 7

"- 8" is impossible for width.

So, width x = 7

Length = (x+1) = 7+1 = 8

A spinner is separated into 4 equal pieces, as shown below:
kakasveta [241]

Getting black is 1/4 of the percentage, and spinning it 10 times gives us 10/40, because there are 40 possible colors to land on when u spin it 10 times. The last spin, is just like any other time you spin it. just because it's the last spin, doesn't make the black sector greater. So the answer is 1/4 or 25%.
