Arectangular field is 4 times as long as it is wide. if the length is decreased by 10 feet and the width is increased by 2 feet, the perimeter will be 80 feet. find the dimensions of the original field. the original dimensions are feet long by feet wide.

The original dimensions are: 38.4  feet long by: 9.6  feet wide.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
