The original width was 94.71 cm
The area decreased 33.1%
The equation for the final size is
2X^2 = 1.2 m^2
X^2 - 0.6 m^2
X^2 = 10000 * .6 cm
X = 77.46 cm (this is the width)
The length is 2 * 77.46 = 154.92 cm
The original length was 154.92 + 34.5 = 189.42 cm
The original width was 189.42 / 2 = 94.71 cm
The original area was 94.71 * 189.92 = 17939.9 cm^2
The new area is 79.46 * 154.92 = 12000.1 cm^2
The difference between the original and current area is 17939.9 - 12000.1 = 5939.86 cm^2
The percentage the area decreased is 5939.86 ' 17939.9 = 33.1%
