The area of a rectangle is the product of width and length. If a rectangle has length 15m radical 9m and width radical 3m, which of the following is the area of the rectangle?
45m^2 radical 3
45m radical 3m
135m^2 radical 3
135m radical 3m
By 'radical 3' I assume you mean square root of 3.
In which case the area of the rectangle would be given by
15*sqrt(9) x sqrt(3)
Which gives you 45*sqrt(3)
