Part 1 out of 2 A patio in the shape of a rectangle , is fenced on all sides with 94 feet of fencing . The patio is 7 feet less
wide than it is long. I feet ( -7 feet What information can be used to solve the problem ? How can you find the information ? You need the select and select of the patio . You can write algebraic expressions for the length and width Use the expressions in the formula for the ( select ) rectangle , and then solve to find the length and the width .
First of all, you should notice that <em>no problem is posed</em>. A description is given, but no question is asked about it.
_____
If we assume that the length and width of the patio are desired, then those are the selections for the first two boxes.
The only other characteristic of the situation that is provided is the <em>perimeter</em>. So the formula for perimeter is the only one that can be usefully used.
If we add the equations it looks like -5y + 8x + 5y + 2x = -18+58 so 10x=40 so x=40/10=4 now let's replace x by 4 in the second equation 5y +2*4=58 5y=58-2*4=58-8=50 so y=50/5=10 so (x, y) = (2, 10)
