Question

A field is in the shape of a rectangle. The width of the field is 28 metres, measured to the nearest metre.

a) Work out the upper bound of the width of the field. The length of the field is 130 metres, measured to the nearest 5 metres.

Answer 1

The upper bound of the width of the field is 28.5 metres.

Step-by-step explanation:

To find the upper bound of the width of the field, we need to consider the possible range of values. The width is measured to the nearest metre, so the actual width could be anywhere from 27.5 metres to 28.5 metres. Since we're looking for the upper bound, we use the higher value, which is 28.5 metres.
