A larger, expanded rectangle is indicated by dashed lines, encompassing the original rectangle and illustrating the expanded area. * **Lines:** The original rectangle is formed by solid lines. The expansion is depicted by dashed lines extending from the original rectangle's right and bottom sides. * **Labels and Annotations:** * The length of the original rectangle is labeled as "40 米" (40 meters) along its top side. * The width of the original rectangle is labeled as "30 米" (30 meters) along its left side. * The increase in length (expansion to the right) is labeled as "10 米" (10 meters) outside and to the right of the original rectangle's top side. * The increase in width (expansion downwards) is labeled as "10 米" (10 meters) outside and below the original rectangle's left side. * **Relative Position and Direction:** The dashed lines indicate an expansion of the original solid-line rectangle towards its right side and downwards. The "10 米" labels clearly show the dimensions of this expansion along both the length and width axes. **Question Stem:** 龙门小学高年级的学生参加校园集体舞表演，每横排人数同样多，每竖排人数也同样多。依依的位置从左往右数排第8，从右往左数排第15；从前往后数排第11，从后往前数排第13。参加表演的学生有多少人？ **Question Stem:** 好日子酒店要在门口宽4米的台阶上铺上红地毯 (如下图)，至少需要多少平方米的红地毯？ (单位：米) Translation: Good Day Hotel needs to lay red carpet on the steps at its entrance, which are 4 meters wide (as shown in the figure below).

This represents the width of the carpet. * The total vertical height of the stairs is indicated by an arrowed line on the right side, labeled "2". This represents the total rise. * The total horizontal depth (or run) of the stairs is indicated by an arrowed line on the right-bottom side, labeled "3". This represents the total tread length. * The stairs are shown in a way that suggests the carpet would cover the horizontal top surface (tread) and the vertical front surface (riser) of each step.
