A coordinate grid is a graph with an x- and y-axis that you can plot coordinates on. To draw a coordinate grid, get a piece of graph paper or draw your own grid lines on a blank piece of paper using a ruler. Then, draw a horizontal line through the middle for the x-axis and a vertical line down the center for the y-axis. Finally, number the points on each axis, starting with “0” where the x- and y-axis intersect. When you number your grid, the numbers above and to the right of the 0 will be positive, while the numbers below and to the left of the 0 will be negative. on the graph. You should have been given coordinates for each vertex, or angular point, of the polygon you’re trying to find the perimeter of. Each coordinate should look something like “(1,2)." Use the numbers you marked on the coordinate grid to plot each of the coordinates. When you’re finished, connect the points with straight lines to see the shape of the polygon you’re working with. You’ll need to know the length of each side of the polygon to determine its perimeter. For vertical or horizontal sides, simply count how many units there are between the points on each end. Then, write down the number next to that side so you can refer to it later. For example, if you’re trying to find the length of a horizontal side, start at one end and count the number of boxes between that point and the other end. If you counted 6, that would mean the length of that side is 6 units. to find the length of diagonal sides. Unfortunately, you can’t count the units on a grid to find the length of diagonal sides like you can with vertical or horizontal sides. Instead, you’ll need to use the distance formula, which is d=(x2−x1)2+(y2−y1)2{\displaystyle d={\sqrt {(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}}}. Just plug in the values of the x and y coordinates for the 2 points at the ends of the side you’re trying to find the distance of and solve to find the length.  For example, if you’re trying to find the distance (length) between 2 points with the coordinates (4,7) and...

How would you rephrase that briefly using Indonesian?
