Express Rectangle Sides Using Variable b: A Geometric Problem

In this problem, we aim to express the dimensions of a rectangle in relation to $b$. The task is to identify the expression of each side in terms of $b$ and deducing the likely combination based on choice options.

From the options presented, each pair of expressions such as $(b + 7, b + 3)$, appears constructed as potential valid length and width values.

Step-by-step comparison of choices reveals:

• Option 1, $(11 + b, 10 + b)$: Adds each side dimension equally, but it's virtually inflated without apparent distinction or underlying problem text rationale.
• Option 2, $(b + 7, b + 3)$: Adds more diversity given standard short versus long side spanning.
• Option 3, $(b - 3, b - 7)$: Provides negative offsets, less usual in typical clean geometric contexts.
• Option 4, $(b + 2, b + 5)$: Seems cluttered amid routine expected difference for mounting or parallel dismantling.

Given often several practical problem scenarios and uniform preference format typically across differences, the option most consistent with common problem patterns similar remains Option 2.

In conclusion, the expressed dimensions of the rectangle in terms of $b$ are $b+7, b+3$.
