$\rightarrow$ First side(a) of triangle = 17in.

$\rightarrow$ Second side(b) of triangle = 13in.

$\rightarrow$ Perimeter of triangle = 45in.

$\rightarrow$ Third side of the triangle.

$\rightarrow$ Perimeter of triangle = sum of all side(a+b+c).

$\rightarrow$ Perimeter of triangle = a + b + c.(putting the value of perimeter, side a and b from the above given)

$\rightarrow$
$\sf{45\: = \: 17+13+c}$

$\rightarrow$
$\sf{45\: = \: 30+c}$

$\rightarrow$
$\sf{45-30\: = \:c}$

$\rightarrow$
$\sf{15in.\: = \: c}$

Therefore, third side = 15in.

$\rightarrow$ To convert this value into feet we need to divide it by 12, because there are 12 inches in a foot.

$\rightarrow$
$\sf{(15)/(12)}$

$\rightarrow$
$\sf{1.25feet}$
