Question

The sides of a triangle are 7/2 cm, 11/4 cm and 16/5 cm. Find its perimeter.

Answer 1

Perimeter of a triangle is the sum of each side

So here the perimeter is 7/2+11/4+16/5
=189/20=9.45cm

Hope it helps.... :-)

Answer 2

HI !

7/2 + 11/4 + 16/5 = perimeter

lcm ( 2 , 4 , 5) = 20

70/20 + 55/20 + 64/20 = perimeter

Perimeter = 189/20 cm
