the trapezoid below has legs with lengths y feet and one base that is four feet longer than the other base, x.
perimeter of this trapezoid is given by p=2x + 2y + 4 . solve this equation for the leg length, y.
x+4
if the perimeter of the figure is 26 feet and the shorter base, x, is 8 feet, then find the length of the leg, y.

- "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."

care to share were the trapezoid shown is ?
