完整解题讲解---**Question Stem:** 18. 中国新能源汽车为全球应对气候变化和绿色低碳转型作出了巨大贡献. 为满足新能源汽车的充电需求, 某小区增设了充电站, 题 18 图是矩形 PQMN 充电站的平面示意图, 矩形 ABCD 是其中一个停车位. 经测量, ∠ABQ = 60°, AB = 5.4 m, CE = 1.6 m, GH ⊥ CD, GH 是另一个车位的宽, 所有车位的长宽相同, 按图示并列划定. 根据以上信息回答下列问题: (结果精确到 0.1 m, 参考数据 √3 ≈ 1.73) (1) 求 PQ 的长 (2) 该充电站有 20 个停车位, 求 PN 的长 **Diagram Description:** * **Type:** Plan view diagram of a rectangular area containing multiple parallel rectangular/parallelogram shapes. * **Main Elements:** * A large outer rectangle labeled PQMN. * Inside the large rectangle are several parallel slanted rectangles/parallelograms representing parking spaces. * One parking space is specifically labeled ABCD. * Points labeled: P, Q, M, N (vertices of the outer rectangle); A, B, C, D (vertices of one parking space); E, F, G, H (other points within or related to the parking spaces). * Labels on the bottom edge QM: QB = 2.7, BE = 3.2 (these seem to be lengths along the edge). * Label for length: AB = 5.4 m. * Label for length: CE = 1.6 m. * Angle label: ∠ABQ = 60°. * Annotation: GH ⊥ CD (GH is perpendicular to CD). * Text "题 18 图" below the diagram. **Other Relevant Text/Information:** * "GH 是另一个车位的宽" (GH is the width of another parking space). * "所有车位的长宽相同, 按图示并列划定" (All parking spaces have the same length and width, arranged side-by-side as shown). * Instruction: "结果精确到 0.1 m" (Result rounded to 0.1 m). * Reference data: "参考数据 √3 ≈ 1.73" (Reference data √3 ≈ 1.73). **Questions:** (1) 求 PQ 的长 (Find the length of PQ). (2) 该充电站有 20 个停车位, 求 PN 的长 (This charging station has 20 parking spaces, find the length of PN).
