let the total length of two equal sides be 3x+3x
the length of the base be 2x
here x is a ratio constant
BTP
=>3x+3x+2x=32
=>8x=32
=>x=32/8
=>x=4
total length of the to equal sides = (3x4)+(3x4)
=12+12=24
length of base=2x4=8
area of the triangle=1/2x(8)^2cm
=1/2x64cm
=32sq cm
ans:32sqcm

Answer:
hii,I hope this will help you
as the isosceles triangle has two equal sides
ratio of side and base=3/2
then the equal side be 3x and base be 2x
then
perimeter=3x+3x+2x
32=8x
4=x
then equal side=4*3=12 and base=4*2=8
then area of isosceles triangle by heron formula
semi perimeter=32/2=16cm
√{16(16-12)(16-12)(16-8)
√{16*4*4*8}
4*2*2*2√2
32√2 is the area of triangle
