Answer:
other sides of triangle is eaual
so a+b+c=35
base = 12
in this case bc is the base so
b=a
2a = 35-12
a = 23/2
a = b = 11.5 cm
2s= a+b+c
s=12+11.5+11.5/2
s=35/2
s= 17.5
use herons formula to find area
area =√[s (s – a)(s – b)(s – c)], i gave all the values to you
you should do this by applying those values in formula
answer is 58.86 cm^2
