Question

The length of the sides of a
triangles are integers and its
area is also integer. The
length of one side is 21 and
perimeter is 48, then the
length of shorter side is​

Answer 1

2(l+b)=48

2(21+b)=48

21+b=24

b=3

Answer 2

hey mate here is ur answer =

a+b+c=48

a+b+21=48

a+b=27.

now condition for triangle to be formed is

sum of two sides must be more then third side.

And as area is an integer a or b one must be an even number .

a=6 and b=21 is the smallest set satisfying the equation.

Length of shorter side is 6.

hope it helps.
