First, get the sides of the triangle. Obviously they are 50cm, 40cm and 30 cm. The perimeter is 120 cm and we have used only 4 integers which are 5, 4, 3 and 0. Second, use the Heron's formula for solving this kind of problem when 3 sides of the triangle are given. The formula is:
Area=SQRT(s(s-a)(s-b)(s-c)), where s=(a+b+c)/2 or perimeter/2. s= 120cm/2= 60cm, therefore, Area = sqrt (60 (60-50)(60-40)(60-30)) = 600 square cm
I hoped I was able to help....

I wouldn't worry about one problem.
If you don't know guess.
If you don't want to guess pass the question by.
One unanswered question will not change your entire life.
Get help from your teacher or your parents if you don't know how to do any of your home work.
Peace.
