Question

the sides of a triangle are in the ratio 4:5:5 and its perimeter is 168m . find the area of the tringle.

Answer 1

okkkkkk.....

4x + 5x + 5x = 168m
14x=168
x= 12m

fist side is 4×12 = 48
second side 5×12=60
third side 5×12=60

herone formula applied

s=168/2
s=84
area =√s(s-a)(s-b)(s-c)

area = 2592√35 answer
