This question was asked and answered about two weeks ago. Were you the person who posted the question? Did you see the answer?
There is a formula for the area of a triangle in terms of the lengths of three sides, which I provided in my previous answer. Use that formula.

Divide the area by 70 m^2 per can for the number of cans.

would it be 1878.58 divided by 70m^2 =
4900/1878.58= 2.6 so 3 cans
