Last year mr petersons rectangular garden had a width of 5 meters and an area of 20 square meters. This year, he wants to make the garden three times as long and two times as wide

Step-by-step explanation:

A=LW, given A=20, W=5

5L=20

L=4m

This year the length will be 3L=3(4)=12m

and W this year will be 2W=2(5)=10m

So the new garden will be 12m by 10m (with an area of 12(10)=120m^2)

i would need to see the dot plot : )

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
