Answer:
let the isosceles triangle side be x
it's perimeter is 32 cm
side = 4cm ,xcm,xcm
perimeter = 4+x+x
32. = 4+2x
32-4. = 2x
28. 2x
28/2. = x
14 =x
the equal side is 14,14 cm
by heron's formula
s= a+b+c/2
s= 14+14+4/2
= 32/2
= 16
area =√ s(s-a)(s-b)(s-c)
= √ 16 (16-14)(16-14)(16-4)
= √ 16×2×2×12
=√2×2×2×2×2×2×2×2×3
= 2×2×2√3
= 8√3
