One side of a kite is 3 cm less than twice the length of another side. If the perimeter is 36 cm, find the length of longer side.

let the length of two of the sides   =   x     cm

then the length of the other two sides   =   2x - 3      cm

x  +  x  +  2x - 3  +  2x - 3   =   36

6x - 6   =  36

6x   =   42

x   =   7

and the length of the longer side   =   2(7) - 3   =   11     cm
