A rectangle's width is one-seventh its length, and its perimeter is 224 m. Find the dimensions of the rectangle.​

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

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
