Well, darling, if you shaded all but three eighths of the rectangle, then the shaded area is 5/8 of the total rectangle. To find the percentage of the rectangle that is not shaded, you subtract the shaded area from 100%. So, 100% - 62.5% (5/8 as a percentage) = 37.5%. Voilà, 37.5% of the rectangle is not shaded.
You can make a rectangle by using two squares
You haven't said what the 7 eighths are 7 eighths of, and that's going to make all the difference in the answer. -- If it's 7 eighths of a millimeter, then there are 7 eighths of a millimeter in it. -- If it's 7 eighths of an inch, then there are 22.225 millimeters in it. -- If it's 7 eighths of a foot, then 266.7 millimeters. -- If 7 eighths of a meter, then 875 millimeters. -- If 7 eighths of a mile, then 1,408,176 millimeters. -- If 7 eighths of a day, or 7 eighths of a pound, or just plain 7 eighths with no unit, then none.

Yes, Four Triangles make a rectangle.
That would be 5 eighths. Since 1/2 is equal to 4 eighths, you simply add 1 and 4 together to make five. (The eighths part stays the same)
To convert one fourth to eighths, you need to multiply the denominator by 2. So, one fourth is equal to two eighths. Therefore, it takes two eighths to make one fourth.
= 5 / 4 * 6 / 4 = 30 / 16 = one and seven eighths
If it is a rectangle then: 2*(3.4+6.125) = 19.05 which is its perimeter
