Question

A triangular park PQR has sides a= 120 m, b = 80 m and c = 50 m , then the value of (s-b) is *

a) 45 m
b) 5 m
c) 20 m

Answer 1

Answer:

Given that,

A=120m

B=80m

C=50m

S=a+b+c/2

=120m+80m+50m/2

=250m/2

=125m

Now as per ur question

(s-b)

=(125m-80m)

=(45m)

Answer 2

Answer:

option A 45 is the correct answer

Step-by-step explanation:

here S = (120+80+50)/2

=125

so (S-b)=125-80

=45.
