<u>Finding x</u>
- 2x - 28 = x/2
- 3/2x = 28
- 3x = 56
- x = 56/3 = 18.66666667
- The exact side length of the small square is <u>18.66666667 cm</u> and the exact side length of the big square is <u>37.3333334 cm</u>.
- The approximate side length of the small square is <u>18.7 cm</u> and the approximate side length of the big square is <u>37.3 cm</u>.
x = 45%
