The perimeter of a rectangle can be found using the equation P = 2L + 2W where P is the perimeter, L is the length, and W is the width of the rectangle. Can the perimeter of the rectangle be 60 units when its width is 12 units and its length is 18 units? A) No. If the rectangle has L=18 and W=12, P would not equal 60.
B) No. the rectangle cannot have P=60 and L=18 because L+W is less than 24.
C) Yes. The rectangle can have P=60 and L=18 because 60=24+18.
B) Yes. The rectangle can have P=60 and L=18 because P=2(18)+2(12) would equal 60. ​

Step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
