    Panjang segi empat A= 16,81cm÷2=8.49cm
    Panjang segi empat B =8.49cm+1.5cm=9.99cm
    Perbezaan antara segi empat A dan B =1.5cm

    luas A = 16.81cm^2,
    satu sisi A = 16.81/2 = 8.405 = 8.41cm

    sisi B = 8.41+1.5 = 9.91cm
    luas B = 9.91x2 = 4.955cm^2

    16.81^2=4.1
    4.1+1.5=5.6
    5.6^2=31.36-16.81=14.55
