If the length is 3 times the width, then to find the width, you need to multiply the length by 3:
1) 7 * 3 = 21 (m) – width.
To find the perimeter, you need to find the sum of two lengths and two widths:
2) 21 + 21 + 7 + 7 = 42 + 14 = 56 (m) – perimeter.
To find the area, you need to multiply the length by the width:
3) 21 * 7 = 147 (m ^ 2) – area.
Answer: perimeter = 56 m; area = 147 m ^ 2.
