Answer:
Step-by-step explanation:
The length of a chalkboard, l = 1.7
The width of a chalkboard, b = 0.9 m
We need to find the area of the chalkboard. The formula for the area of a rectangle is given by :
So, the area of the chalkboard is equal to 
.
No this is not a triangle. With these lengths
999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999
You have to add up all the numbers then divide by the amount of numbers there are
24+38+19=81
81/3=27
The average is 27
You would have to first times .03 times 10 then take that times 30,000 which should equal 900
