Answer
Length of the shorter side = 12 cm
Length of the longer side = 21 cm
Work Step by Step
length of the shorter side = x
length of the longer side = 2x - 3
2x + 2 (2x - 3) = 66
2x + 4x - 6 = 66
6x = 66 + 6
x = 72 / 6
x = 12 cm
Length of the longer side:
2 ( 12 ) - 3 = 24 - 3 = 21 cm
Length of the sides of the kite: 12 cm, 12 cm, 21 cm, 21 cm
