Enlarge the drawing onto the larger grid. What scale is used?

To enlarge the drawing, we need to determine a scale factor. The original drawing is on a 4 × 4 grid. The target grid is a 5 × 5 grid. Typically, when enlarging drawings on a grid, an integer scale factor like 1:2 (meaning each dimension is doubled) is used. However, if we apply a 1:2 scale to the original drawing (which occupies roughly a 4 × 4 area), it would become an 8 × 8 drawing, which would not fit on the provided 5 × 5 grid. Given the instruction "Enlarge the drawing onto the larger grid" and the specific grid sizes, the problem is ambiguous. If the drawing must fit the 5 × 5 grid and be an enlargement, the scale factor would be (5)/(4) or 1.25. However, drawing with a non-integer scale on a grid is not standard for this type of problem. Assuming the most common integer enlargement scale for such exercises, which is 1:2, we will draw the robot with each dimension doubled. We will draw as much of the 1:2 enlarged robot as fits within the 5 × 5 grid. Scale used: 1:2 Here's how the drawing would be enlarged with a 1:2 scale, mapping each square from the original grid to a 2 × 2 block of squares in the new grid. Since the 5 × 5 grid is smaller than the required 8 × 8 for a full 1:2 enlargement, only a portion of the enlarged robot will fit. The drawing below represents the robot enlarged by a scale of 1:2, with the parts that fit within the 5 × 5 grid. ` +---+---+---+---+---+ | | | | | | +---+---+---+---+---+ | | | | | | +---+---+---+---+---+ | | | | | | +---+---+---+---+---+ | | | | | | +---+---+---+---+---+ | | | | | | +---+---+---+---+---+ ` (Self-correction: I cannot actually draw on the grid in text. I will describe the drawing process and state the scale.) To draw the enlarged robot with a 1:2 scale: 1. Each square in the original grid corresponds to a 2 × 2 block of squares in the new grid. 2. For example, if the robot's body is 3 squares wide in the original, it would be 3 × 2 = 6 squares wide in the enlarged version. 3. If the robot's body is 1 square high in the original, it would be 1 × 2 = 2 squares high in the enlarged version. 4. The head and neck extend about 3 squares above the body in the original, so they would extend 3 × 2 = 6 squares in the enlarged version. Since the 5 × 5 grid is smaller than the 8 × 8 area required for a full 1:2 enlargement of the 4 × 4 original, the entire enlarged robot cannot be drawn on the provided grid. However, the most common scale for such enlargement problems is 1:2. That's 2 down. 3 left today — send the next one.
