Respuesta :
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
Answer:
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
