Answer: let the ratio be 5x,7x,10x
5x+7x+10x=440
22x=440
X=440÷22
X=20
5x=5×20=100
7x=7×20=140
10x=10×20=200
S=perimeter/2
S=440/2
S=220
Area of triangle=√s(s-a)(s-b)(s-c)
=√220(220-100)(220-140)(220-200)
=√220(120)(80)(20)
=6499.23
Step-by-step explanation:a,b,c are the sides. You can expand the numbers and make pairs of them and take it out of the root
