Find circumference and area of the rhumbline ABCD if the short side AD of which has a length of 5 cm, and the heel of the height from D leading to the AB side divides the AB side into two sections of 3 cm and 4 cm.

Correct answer:

o =  24 cm
S =  28 cm2

Step-by-step explanation:

d=5 cm a1=3 cm a2=4 cm  a=a1+a2=3+4=7 cm o=2 (a+d)=2 (7+5)=24 cm
v=d2a12=5232=4 cm S=a v=7 4=28 cm2
