You have a wooden board that measures 54 cm by 90cm. you want to cut the board into identical square pieces with integer side lengths and use all of the wood.

1) find 3 possible side lengths for the squares

2) what’s the largest side length you can choose?

3) how many square pieces will you have?

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
