Ta có hình thoi ABCD; 2đchéo AC;BD vuông góc và cắt nhau tai TĐ  O của mỗi đường

Xét tam giác vuông AOB có:

AO= 1/2 . 9,6=4,8 cm

BO=1.2 . 7,2= 3,6 cm

áp dụng định lí py ta go trong tam giác trên ta được:

AO2+BO2=AB2

=>(4,8)2+(3,6)2 =AB2

=>AB2=36=62

=>AB=6 (vì AB>0)

mà AB+BC+CD+DA

=>chu vi ht = AB+BC+CD+DA=6.4=24cm
