## Geometry Question for Title 1 Schools: Length & Area Question?9) If the length of a rectangle is twice the width of it, what is the length if the area is 72? Area of a rectangle = length x width Area for a rectangle "a" = length "l" x width "w" Since "l" is twice "w", then l = 2w a = l x w 72 = 2w x w
72 = 2w We have to make "w" subject of formula, so we move 2 to the other side. When you move to the other side, addition becomes subtraction, multiplication becomes division, and vice versa.
72/2 = w
36 = w 6 = w If the width is
6, then the |
