Question

the length of a rectangle is fixed at 25 cm. What widths will make the parameter greater than 88 cm?

Answer 1

P = 2W+2L


P = 2W+2(25)


P = 2W+50


So the perimeter expression is 2W+50


Since we want the perimeter to be greater than 88, this means that P > 88 and


2W+50 > 88


2W > 88-50


2W > 38


W > 38/2


W > 19



So the width must be greater than 19 cm

Answer 2

perimeter, not parameter

Answer 3

named after a guy named Peri who had a meter.

Answer 4

so would two meters be pair a meters?

Answer 5

or two medics?

Answer 6

I wouldn't worry about the origins of "perimeter" at the moment.

Answer 7

Just know that "perimeter" means "the distance around something"

Answer 8

In this case, it means the distance around a rectangle
