The width of a rectangle is measured as 12.3 cm, while the length is measured as 28.8 cm. The width measurement could be off by 1.2 cm, and the length could be off by .04 cm. Estimate the maximum possible error in calculating the area of the rectangle.

    width is between 11.1 and 13.5 cm\length is between 28.76 and 28.84 cm

    area is thus between 319.236 and 389.34 cm^2

    That's 354.288 ± 35.052 cm^2

    use correct significant digits
