Answer 2

                                                     ANSWER

A Triangle has a perimeter of 32 cm. With 1 of its side is 11 cm and difference of another  2 sides are 5 cm.

So, if we take the second side as X, then the third side will be X+5 or X-5.But I I will take the third side as X+5 for easy.

Hence,

           11+(x)+(x+5)=32

        or, 11+2x+5=32

        or, 2x+16=32

        or, 2x=32-16

         or,2x=16

         or,x=16/2

         or,x=8

Therefore, measurement of 2nd side is 8 and 3rd side is 13.

A/C to the Heron formula,

                                        S=11+8+13/2

                                          S =32/2

                                           S =16
