Answer 1

Answer:

Area of triangle=8 in square root 30

Step-by-step explanation:

P=32cm, A=8cm, B=11cm

C=[32-(8+11)]cm=13cm

s=a+b+c/2 , 8+11+13/2=32/2

=16cm

Triangle=In square root S(s-a)(s-b)(s-c)

=16(16-8)(16-11)(16-13)

=in square root (16×8×5×3) cm2

Area of triangle=8 in square root 30
