Solve P = 2 (l + w) for w. w =

To solve for w, you need to isolate/get the variable "w" by itself in the equation:

P = 2(l + w)     Divide 2 on both sides

    Subtract l on both sides to get "w" by itself

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
