Which is the best equation to use to solve this problem?



The perimeter of a rectangle is 96 ft. The ratio of the length to the width is 7: 5. What are the dimensions of the rectangle?

Let l be the length of the rectangle and w be the width of the rectangle.

To solve this problem, we can use the formula for the perimeter of a rectangle, which is P = 2l + 2w.

Since the perimeter of the rectangle is given as 96 ft, we can write the equation as:

96 = 2l + 2w.

We also know that the ratio of the length to the width is 7:5, which can be written as:

l/w = 7/5.

To solve for the dimensions of the rectangle, we can solve these two equations simultaneously.
