Hello,
I suppose equations are:
x+y=3 (1)
x+2y=9 (2)
(2)-(1)==>y=6
(1)==>x=3-6
x=-3, y=6
Sol={(-3,6)}
If patio is square it means that area of if is

where a is one side
Now we can substitute A=200 and solve eq

a=

a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1
It looks like the first 3 are because they all are blank x2.5 but the last one would be 8x2.5=20..
The wrongest way is to mark an ' X ' on the side of the boat.
Answer:
Length = 45 m
Width = 185 m
Step-by-step explanation:
Given:
Perimeter of rectangular rug = 460 m
width of the rug is five meters more than 4 times the length
To find:
Width and length of rug = ?
Solution:
Let the length =
m
As per given statement,
Width =
m
Formula for perimeter of a rectangle = 

Width =
m
Width = 
So, the answer is:
<em>Length = 45 m</em>
<em>Width = 185 m</em>
<em></em>
