Answer: 1591
Step-by-step explanation: Let's look for the clues. A rectangle has 4 sides, 2 sides are equal length and so are the other 2 sides of a rectangle.
Perimeter of a rectangle is Side 1 + Side 2 + Side 3 + Side 4.
Side 1 and Side 3 (for example) are the longer sides of the rectangle, they will be equal.
Side 2 and 4 (for example) are the shorter sides of the rectangle, they will be equal.
Sides 1 + 2 + 3 + 4 = 160
Side 1 and Side 3 are equal to "x + 6", or in plain english 6 feet longer than the other sides.
Side 2 and 4 are equal to "x"
Adding them all together
x + x + x+6 + x+6 = 4x + 12 = 160
4x + 12 = 160 is now a much simpler algebra problem.
4x = 148
x = 37
So the shorter sides are each 37, the longer sides are each 43.
The area of a rectangle is length times width.
37 x 43 = 1591 ft squared
