Rectangular garden

The sides of the rectangular garden are in a ratio of 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
