Question

Find the semi-perimeter of a triangle of sides 40 m, 24 m, 32 m.​

Answer 1

Answer:

Let a= 40 m

b= 24m

c= 32m

now,

semi perimeter (s) = (a+b+c)/2

= (40+24+32)/2

= 96/2 m

= 48 m

Hence, the semi perimeter of the given triangle is 48 metre.

Answer 2

Answer:

Let a be 40 metres b be 24 metres and c be 32 metres

Therefore, semi perimeter

=a+b+c/2

=(40 + 24 + 32/2) metres

= (96/2) metres

= 48 metres
