Find the area of the shaded picture??

12 squared unit

Step-by-step explanation:

12 Units

Step-by-step explanation:

Count up the full shaded squares and you'd get 9, Then take each half and add them together to make a whole. 6 half's make 3 wholes. Then add 9+3 :)

- "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."

it would take 7/10 of an hour too fill the pool.
