PSY has a stable where he owns and feeds his horses like the one below.
The old stable is shaped like a rectangle. Currently, its perimeter is 240 meters.
PSY wants to expand the old stable so he can feed more horses. He wants to double the old stable's length and leave the width unchanged. After doubling the length, the new stable's perimeter would be 400 meters.
What is the old stable's length and width? Assume length is greater than width. Model this situation with a pair of simultaneous linear equations.
