Question

write the perimeter of a triangle with a example​

Answer 1

s+s+s

ie, sum of the three sides

eg: AB=3,BC=2andCA=5

then perimeter=3+2+5=10

Answer 2

formula for this is a+b+c where a,b ,c are side of triangle

suppose a= 12cm , b = 23cm and c = 11cm

so perimeter will be a+ b+c

=12+23+11

= 46 cm
