The area of a rectangle is found using this formula: a = l × w if the area is 54cm² and the width is 18cm, solve for l.

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
