Question

A field is in the shape of a rectangle.

The length of the field is 340 m, to the nearest metre.
The width of the field is 117 m, to the nearest metre.
Calculate the upper bound for the perimeter of the field.

Answer 1

914 meters

Explanation:

340*2+117*2

680+234

=914 m

Hope this helped! :)

Answer 2

Explanation:

the perimeter of a rectangle is

2×length + 2×width.

length and width are given to the nearest meter.

that means doubling them could add an additional meter due to rounding.

so the upper limit or maximum possible perimeter is

2×340 + 1 + 2×117 + 1 = 680 + 234 + 2 = 916 meters
