Answer:
Sum of ratio= 5+8+12=25
perimeter=sum of 3 sides=250
sides=5/25×250=50cm
8/25×250=80 cm
12/25×250=120cm
Are of triangle herons formula
A=√s(s-a)(s-b)(s-c)
s= semi perimeter=a+b+c/2
. =50+80+120/2
=250/2
=125
A=√125(125-50)(125-80)(125-120)
=√125(75)(45)(5)
=√125(16875)
=√2109375
=1452.368 cm2
