Answer:
98 m long and 14 m wide
Step-by-step explanation:
If the width is one seventh its length, the length is 7 times greater than the width.
Let the width be represented by w, and let the length be represented by 7w.
Use the perimeter formula, p = 2l + 2w.
Plug in 224 as the perimeter, 7w as l, and solve for w:
p = 2l + 2w
224 = 2(7w) + 2w
224 = 14w + 2w
224 = 16w
14 = w
The length is 7 times greater, so multiply this by 7:
14(7)
= 98
So, the rectangle is 98 m long and 14 m wide
