the measures of length of the sides of a triangle are integers and that of its area is also an integer.one side is 21cm,and perimeter is 48 cm.the measure of shortest side is ---------- a)16 b)5/2 c)19 d)3/2

given that sides are intezers

here the options are 16,5/2,19,3/2

hence there are 16,19

we know that sum of any two sides is greater than the third side

if we take 16

the sides are 21,16,11

if we take 19

the sides

are 21,19,8

the answer is 16 

Answer is a)16.
