Answer:

The rectangle dimensions are 20 m by 80 m

Step-by-step explanation:

Let W represent the width and L the length.  Then W = 0.25L.

The perimeter, P, is 200 m.  The formula for that is P = 2W + 2L.

Substituting 0.25L for W, we get:

2(0.25L) + 2L = 200 m, or (after mult. both sides by 2):  L + 4L = 400 m

Then 5L = 400 m, and L = 80 m.  Thus, W = 0.25(80 m) = 20 m.

The rectangle dimensions are 20 m by 80 m

Natali [406]

Answer: 36

Step-by-step explanation:

One roll is of length = 9 feet

1 foot = 12 inches

9 feet = 12 *9 = 108 inches

Since there are 5 rolls

So, total length of 5 rolls = 108 * 5 = 540 inches

Since we are given that A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length.

We are supposed to find . What is the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon

So, number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon:

Hence the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon is 36
