Question

Given that if the field is a triangle
ABC which is a night, angled at B. Which
of the following is true for the giventriang-
ular field with the given dimensions?
A
Visom
30ml
B
253cm
Both perimeter and area is rational

Answer 1

Answer:

Let a,b,c be the sides of the given triangle and 2s be its perimeter such that

a=8 cm, b=11 cm and 2s=32 cm

Now, a+b+c=2s

8+11+c=32

c=13

Therefore,

s−a=16−8=8,s−b=16−11=5,s−c=16−13=3

Hence, area of given triangle =  

s(s−a)(s−b)(s−c)

​

=

16×8×5×3

​

=8
