Question

the lengths of th3e sides of a triangle park are 7.5 cm,9.4m and 6.6.find the length of iron chain required to fence it with 4 rounds

Answer 1

Answer:

lengths of the three sides of the park

first side=7.5 cm

second side=9.4 cm

third side=6.6 cm

now,

perimeter = (7.5+9.4+6.6) cm

= 23.5 cm

Therefore perimeter of the triangular park is 23.5 cm.

now,

length of iron chain required to fill it with 1round is 23.5 cm.

Therefore length of iron chain required to fence the park with fore complete rounds is (23.5*4) cm = 94 cm.
