Answer:

A rectangle with a length of 9 cm and a width of 3 cm.

Step-by-step explanation:

In similar rectangles, the ratios of corresponding sides are equal.

\\\frac{length}{width} → \frac{21}{7} = \frac{3}{1} and \frac{9}{3} = \frac{3}{1}

Answer:

48x² + 24x + 3

Step-by-step explanation:

Width = (4x + 1) in

Length = 3 *width = 3*(4x + 1) = 3*4x + 3*1

           = (12x + 3) in

Area of rectangle = length * width

                             = (12x + 3) (4x + 1)

                             = 12x *4x  + 12x *1  + 3*4x  + 3*1

                             = 48x² + 12x + 12x + 3

                              = 48x² + 24x + 3
