X, y - the lengths of the sides of the pathway
The area of a rectangle is the product of the lengths of its sides. The area is 350 m².
The perimeter of a rectangle is two times the sum of the lengths of its sides. The perimeter is 90 m.
Substitute 45-x for y in the first equation:
The dimensions of the pathway are 10 m by 35 m.
The length of the pathway is 35 m.
