what do you call an animal that eats plants?\n1. one side of a rectangle is 2 times the length of another…

Explanation:

Step1: Set up equations for rectangle sides

Let the shorter side of the rectangle be $x$ feet and the longer side be $y$ feet. We know that $y = 2(x - y)$ and $y - x=7$. From $y - x = 7$, we have $y=x + 7$. Substitute $y=x + 7$ into $y = 2(x - y)$: $x + 7=2(x-(x + 7))$ is incorrect. The correct relationship from "One side of a rectangle is 2 times the length of another side. The difference in their lengths is 7 feet" should be: Let the shorter side be $x$ and the longer side be $y$. We have $y = 2x$ and $y-x=7$. Substitute $y = 2x$ into $y - x=7$, we get $2x-x=7$, so $x = 7$ feet.

Step2: Find the length of the other side

Since $y = 2x$ and $x = 7$, then $y=2\times7 = 14$ feet.

Step3: Calculate the perimeter

The perimeter $P$ of a rectangle is given by $P=2(x + y)$. Substitute $x = 7$ and $y = 14$ into the formula: $P=2(7 + 14)=2\times21 = 42$ feet.
