A student measures the length and width of a rectangular glass slide. The recorded dimensions are:
length=52±2 mm \text{length} = 52 \pm 2\text{ mm} length=52±2 mm width=28±3 mm \text{width} = 28 \pm 3\text{ mm} width=28±3 mmWhich of the following is the best estimate for the area of the glass slide?
