Answer:
44 units
Step-by-step explanation:
When you perform a dilation on a figure, all of the side lengths of the figure get multiplied by the scale factor. This means that the perimeter is also multiplied by that scale factor. Since in this case that scale factor is 2, the new perimeter is 22*2=44 units. Hope this helps!

Answer:
The new height of the water is 6.167 m
Step-by-step explanation:
The volume of the pool is given by the product of it's three dimensions width, length and height. In the initial situation we have a pool with width equals 4m, the length equals 6m and height of the water of 2m. So we can find the volume as seen bellow:
initial volume = length*width*height = 6*4*2 = 48 m^3
Then 100 m^3 were added to the pool, so it's new volume will be the sum of the initial volume and the added water so we have:
final volume = initial volume + 100 = 48 + 100 = 148 m^3
Since the only dimension that can change in this situation is the height ofthe water we can use the formula for the volume to find the new height, as seen below:
final volume = length*width*(new height)
148 = 6*4*(new height)
6*4*(new height) = 148
24*(new height) = 148
new height = 148/24 = 6.167 m
The new height of the water is 6.167 m
