Asked by Michelle

The width of a rectangle is fixed at 21cm. What lengths will make the perimeter greater than 80cm.

Please help with this word problem I do not even know where to begin.
Answered by Ms. Sue
The perimeter is the distance around the rectangle.

P = 2L + 2W

Two widths = 42 cm.

80 - 42 = 38

38/2 = 19

The length must be over 19 cm.
