Let l₁,l₂,…,l₁₀₀ be consecutive terms of an arithmetic progression with common difference d₁, and let w₁,w₂,…,w₁₀₀ be consecutive terms of another arithmetic progression with common difference d₂, where d₁d₂=10. For each i=1,2,…,100, let Rᵢ be a rectangle with length lᵢ, width wᵢ and area Aᵢ. If A₅₁−A₅₀=1000, then the value of A₁₀₀−A₉₀ is __________.
