<span>Simplifying 8k + 2m = 3m + k Reorder the terms: 8k + 2m = k + 3m Solving 8k + 2m = k + 3m Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1k' to each side of the equation. 8k + -1k + 2m = k + -1k + 3m Combine like terms: 8k + -1k = 7k 7k + 2m = k + -1k + 3m Combine like terms: k + -1k = 0 7k + 2m = 0 + 3m 7k + 2m = 3m Add '-2m' to each side of the equation. 7k + 2m + -2m = 3m + -2m Combine like terms: 2m + -2m = 0 7k + 0 = 3m + -2m 7k = 3m + -2m Combine like terms: 3m + -2m = 1m 7k = 1m Divide each side by '7'. k = 0.1428571429m Simplifying k = 0.1428571429m</span>

Sliva [168]

Answer:

The length of the long side of the rectangle is 38 ft.

Step-by-step explanation:

If we test out all possible factors, we will see that 15 x 38 is the most fitting.

Perimeter: 15 + 15 + 38 + 38 = 106 ft.

Area: 15 x 38 = 570 square ft.

38 ft. is the measurement of the long side and 15 ft. is the measurement of the smaller side.
