A yard

Yevgen is fencing in a yard that is 30 meters longer than it is wide. The yard will have an area of 1000 m2. Find its width and length.

Correct answer:

y =  50 m
x =  20 m

Step-by-step explanation:

y=30+x S = xy = 1000  m2  xy=1000 (y30) y=1000  (y30) y=1000 y230y1000=0  a=1;b=30;c=1000 D=b24ac=30241(1000)=4900 D>0  y1,2=2ab±D=230±4900 y1,2=230±70 y1,2=15±35 y1=50 y2=20  y=y1=50=50 m
