Question

Jane is fencing in her backyard. The yard is a rectangular area where one side is the back of her house. The fence will go around only the other 3 sides. The side opposite the house is the same length as the house, which is 25 feet. Jane will use 120 feet of fencing.

Which equation can Jane use to decide how long each of the other two sides of her fence can be?

Answer 1

X=47.5 is the answer

Answer 2

Answer: Jane can use the equation x = 47.5.

Explanation:

From the given information, we know that one side opposite the house is 25 feet, and Jane will use a total of 120 feet of fencing. Since the fence goes around the other three sides of the yard, the combined length of the other two sides will be equal to 120 - 25 = 95 feet.

To determine the length of each of the other two sides, we can set up an equation:

2x = 95

The factor of 2 appears because there are two sides of equal length. By summing up the lengths of the other two sides, we obtain 2x.

Simplifying the equation, we have:

x = 95 / 2

x = 47.5
