Question

If the width of a rectangle is fixed at 19 cm, what lengths will make the perimeter greater than 88 cm?

Answer 1

2(L+19)>88
L+19>44
L>44-19=25

Answer 2

(88 - (2x19))/2 < x
(88 - 38)/2 < x
50/2 < x
25 < x

Each line must be greater than 25 to give a perimetre greater than 88cm.

Answer 3

The length must be greater than 25cm
