Step-by-step explanation:
Given is : The length of the lab is 32 feet and the width of the lab is 48 feet and each 16 feet of the lab equals 2 centimeters on a scale drawing.
So, We will divide the actual length with 16 and multiply by 2 as 16 feet is equal to 2 cm.

Answer:
On Saturday, when 12 weeks passed
Step-by-step explanation:
Tom gets his hair cut every 3 weeks.
David gets his hair cut every 4 weeks.
Find the least common multiple of numbers 3 and 4:
This means that Tom and David will get their hair cut on the same day at 12th week (if the first week when they started has number 0).
You can think in another way:
Tom gets his hair cut every 3 weeks. He got his hair cut after 3 weeks, after 6 weeks, after 9 weeks, after 12 weeks passed.
David gets his hair cut every 4 weeks. He got his hair cut after 4 weeks, after 8 weeks, after 12 weeks passed.
