Rectangular garden

The sides of the rectangular garden are in ratio 1: 2. The diagonal has a length of 20 meters. Calculate the area and perimeter of the garden.

Correct result:

S =  160 m2
o =  53.666 m


o=2 (a+b)=2 (8.9443+17.8885)=24 5=53.666 mo=2 \cdot \ (a+b)=2 \cdot \ (8.9443+17.8885)=24 \ \sqrt{ 5 }=53.666 \ \text{m}
