Question

If the perimeter of a triangle is 32 cm and the sides are 8cm and 11 com find its area.​

Answer 1

Step-by-step explanation:

perimeter =2(l+b)

given

l=11

b=8

area=l×b

=11×8

=88

Answer 2

Answer:

164 cm2

Step-by-step explanation:

= perimeter = a+b+c

=. 32= 8+11+c

=. 32= 19+c

=. 32–19=c

=. 13=. c

hence third side`c`. = 13 cm

13 is the longest side and hence it is hypothenese

height = (13)² –(11)²

= 169–121

=. 41 cm

and therefore.

area = 1/2 × base× height

= 1/2× 8× 41

= 164 cm²
