hi,
for first triangle perimeter = 3 *24 = 72
for second , ( its sides would be half the first one )
perimeter = 3 * 24 /2 = 72 /2
for third , perimeter = 3 * (24/2 )/2 = 72 / 4
and so on
so the sum of perimeter will be =
72 + 72/2 +72 /4 +72/ 8 + .......................
= 72 ( 1 + 1/2 +1/4 + 1/8 +........................)
= 72 { 1/( 1-1/2) } { sum of ∞ g.p. = a/ 1-r )
= 72 *2
= 144 cm
