Grade 11
Question:
Find the area of the parallelogram formed by the lines $y = x$, $y = x + 1$, $y = 2x$ and $y = 2x + 1$.
Step-by-Step Solution
Key Concept: Use the formula: area $= 1/|m - n|$ where $m, n$ are the slopes of the two pairs of parallel lines. Alternatively, find the four vertices by intersecting adjacent sides and compute directly.
