Since the lengths are consecutive odd numbers and the perimeter of the triangle is 51cms. Let x be the unknown length.
so 3x=51 ; x=17 . now the sides can be 15cms, 17cms, 19cms.
check Add them up it is 51cms which is the perimeter and the consecutive odd numbers
The smallest possible length for the third side would be 36 whatever-the-nineteen-and-the-sixteen-unit-is.
My Reasoning/Work:
In a triangle, sides a+b>c, b+c>a, etc.. So, we first add up the two known sides.

Now we know that "c" has to be greater than 35, the closest whole number would be 36. And because the smaller numbers, 19 and 16, are settled, we know just by the fact how just one number is greater than all of the others, using the rule that I listed from the beginning, that this will work.
Exact area will be pir^2 so 81pi is answer or if need to calculate 81 x 3.14
5 tons. 1 ton is 2,000 pounds. 5 * 2,000 is 10,000. 10,000 pounds is heavier than 5000.
