base is 3.2 Find area of this triangle
Part-​

Answer 1

Answer:

32√2cm²

Step-by-step explanation:

let the equal sides be 3x and base be 2x

perimeter=3x+3x+2x

32=8x

x=4

equal sides=12cm

base=8cm

In ΔABC by heron's formula

s=12+12+8/2

 =32/2=16cm

area=√s(s-a)(s-b)(s-c)

       =√16(16-12)(16-12)(16-8)

       =√16×4×4×8

       =4×4×2√2

       =32√2cm²
