Question

side of a triangle are 120cm , 170cm and 250cm. What is the value of semi-perimeters? ​

Answer 1

Answer:

270 cm

Step-by-step explanation:

as it is said that semi perimeters mean half of the perimeter and

perimeter of triangle=sum of all the sides

=120cm+170cm+250cm

=540 cm

:: semi perimeters = half of perimeter

=540/2

270cm

Answer 2

Side-1=120cm
Side-2=170cm
SIDE-3=250cm

Semi perimeter = s1 +s2 +s3 /2
=> 120+170+250/2
=>540/2
=>270
Hence answer is 270 cm
