Question

Q: A rectangular field is 18 metres long and 12 metres wide. Both measurements are correct to nearest metre. Work out exactly the smallest possible area of the field.​

Answer 1

Answer:

Area= length×breadth

= 18 × 12

216metre square is the answer

Answer 2

The smallest possible area of the field is 201.25m²

Given:

Length of the rectangular field = 18m

Width of the rectangular field = 12m

To Find:

The smallest possible area of the field.​

Solution:

The measurement that indicates the size of a region on a planar or curved surface is known as the area.

The closest to 18m can be taken as = 17.5

The closest to 12m can be taken as = 11.5

Therefore,

Using the formula of the area of the rectangle -

Area = length × breadth

Substituting the values -

= 17.5 × 11.5

= 201.25

Answer: The smallest possible area of the field is 201.25m²
