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 answer:

S =  160 m2
o =  53.6656 m

Step-by-step explanation:

a=1x b=2x u=20 m  u=a2+b2 u=x2+4x2=5x2 5x2=202 x=202/5=4 5 m8.9443 m  a=x=8.9443=4 5 m8.9443 m b=2 x=2 8.9443=8 5 m17.8885 m S=a b=8.9443 17.8885=160 m2
o=2 (a+b)=2 (8.9443+17.8885)=24 5=53.6656 m
