A rectangular field has a width of 37 metres, measured to the nearest metre.

a) What is the upper bound of the width?

Answer :

Certainly! Let's go through the question step-by-step to find the upper bound of the width of the rectangular field.

The width of the rectangular field is 37 metres, measured to the nearest metre.

When a measurement is rounded to the nearest metre, it can potentially be up to 0.5 metres more than the measured value before it would round up to the next whole number.

To find the upper bound:

1. Start with the given width: 37 metres.
2. Add 0.5 metres to account for the possible rounding.

So, the calculation would be:

37 metres + 0.5 metres = 37.5 metres

Therefore, the upper bound of the width is 37.5 metres.
