How do you find the length of a side of a square whose area is 300 cm^2?

75cm

Step-by-step explanation:

a square is all 4 sides are equal to each other, so 300 divided by the 4 sides since they are all equal is 75. double check by multiplying 4 by 75 or dividing 400 by 75.

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."
