Rectangular 4624

The lengths of the sides of the rectangular garden are in the ratio of 1: 2. The junction of the centers of adjacent sides is 20 m long. Calculate the perimeter and acreage of the land.

Correct answer:

o =  107.3313 m
S =  640 m2

Step-by-step explanation:

a:b=1:2 2a=b (a/2)2+(b/2)2=202 (a/2)2+(2a/2)2=202 a2+4a2=202 4 a=202 4/(1+4)=8 517.8885 b=2 a=2 17.8885=16 535.7771 o=2 (a+b)=2 (17.8885+35.7771)=48 5107.3313 m k=1/2 a2+b2=1/2 17.88852+35.77712=20
S=a b=17.8885 35.7771=640 m2
