1 Decode or explain what the numbers and letters refer to in this map reference 302700. 2 a Draw a square 4 cm by 4 cm . In the north-west corner, write the figures 3027 in the appropriate square (see Flgure 4.2.1A for where the numbers \( g a \). Hint: Remember ' \( a \) ' before ' 0 '). b Divide this square into four blocks - each 2 cm by 2 cm . c Within each of these four blocks, draw another four blocks - each 1 cm by 1 cm . d Inside this 16 block area that you have constructed, correctly show the position of the place with the reference of 3027DD by shading the correct block. 3 Study Figure 4.2.2 and identify which place in South Africa this topographic map represents.

Let's break down the problem step by step. ### 1. Decode the Map Reference 302700 The map reference "302700" typically refers to a grid system used in topographic maps. Here's how to decode it: - The first two digits (30) usually represent the eastings, which indicate the position east of a specific meridian. - The next two digits (27) represent the northings, which indicate the position north of a specific baseline. - The last two digits (00) often indicate a specific location within the grid square defined by the first four digits. In this case, "302700" refers to a specific grid square on a topographic map, where "30" is the easting, "27" is the northing, and "00" specifies a location within that square. ### 2. Drawing and Dividing the Square #### a. Draw a Square 4 cm by 4 cm To draw a square that is 4 cm by 4 cm, you can use a ruler to measure and draw the sides. In the north-west corner, you will write the figures "3027". #### b. Divide the Square into Four Blocks To divide the 4 cm by 4 cm square into four blocks, each block will be 2 cm by 2 cm. You can do this by drawing two lines horizontally and two lines vertically, each 2 cm apart. #### c. Draw Another Four Blocks in Each Block Within each of the four 2 cm by 2 cm blocks, draw another four blocks, each 1 cm by 1 cm. This means you will draw two horizontal lines and two vertical lines in each of the 2 cm by 2 cm blocks. #### d. Show the Position of 3027DD To show the position of the place with the reference "3027DD", you need to identify which of the 16 blocks corresponds to "DD". - The letters "DD" typically refer to a specific block within the grid. In a standard grid, "A" would be the top-left block, "B" the top-right, "C" the bottom-left, and "D" the bottom-right. - Therefore, "DD" would refer to the bottom-right block of the bottom-right 2 cm by 2 cm block. You can shade this block to indicate the position. ### 3. Identify the Place in South Africa To identify the place represented by the topographic map in Figure 4.2.2, you would need to refer to the specific map provided. Typically, topographic maps in South Africa represent various geographical features, such as mountains, rivers, and towns. If you have access to Figure 4.2.2, look for landmarks, grid references, or any labels that can help you identify the location. Common places represented in South African topographic maps include national parks, cities, and notable geographical features.
