The shape of Colorado is nearly a rectangle. The width is 100 miles less than the length. The perimeter is

about 1320 miles. Find the length and width of Colorado.

Length = 380 miles

Width = 280 miles

Step-by-step explanation:

Width: w

Length: w+100

Perimeter = 2 (length + width)

1320 = 2 (w + w+100)

660 = 2w + 100

2w = 560

w = 280

w + 100 = 380

Length = 380 miles

Width = 280 miles

Answer: width = 280 miles, length = 380 miles

Step-by-step explanation:

width: L - 100

length: L

Perimeter = 2 (Length) + 2 (width)

1320 = 2 (L) + 2 (L-100)

1320 = 2L + 2L - 200

1320 = 4L - 200

1520 = 4L

380 = L

width: L - 100 - --> 380 - 100 = 280

length: L - --> 380
