Answer:
The other side of the Triangle is 13cm
Step-by-step explanation:
The formula for perimeter of triangle=a+b+c
So,
8+11+x=32
19+x=32
x=32-19
x=13cm
If you have to find the are then use the formula
1/2*b*h where b is base and h is height.

Answer:
8root30 cm^2
Step-by-step explanation:
a=8cm, b= 11cm, Perimeter= 32 cm
c= [32-(8+11)]cm=13 cm
s= a+b+c/2 =32/2 = 16cm.
Area of the triangle= root[s(s-a) (s-b) (s-c)]
= root [16(16-8) (16-11) (16-13)]
= root [16 x 8 x 5 x 3] cm^2
Area of triangle = 8root30 cm^2
