Answer:
The length is 52 meters and the width is 23 meters.
Explanation:
Let l stand for length, and w stand for width.
l = 2w + 6
The length is 6 more than twice the width.
2l + 2w = 150
Twice the length plus twice the width is the perimeter of a rectangle.
2(2w + 6) + 2w = 150
4w + 12 + 2w = 150
6w + 12 = 150
6w = 138
w = 23
l = 2(23) + 6
l = 46 + 6
l = 52
