Find the area of a rectangle whose length is four times its width, if its width is four centimeters.

We’re told in the question that the rectangle has a width of four centimeters. The length of the rectangle is four times this. Four centimeters multiplied by four is 16 centimeters. We can calculate the area of any rectangle by multiplying its length by its width. We need to multiply 16 centimeters by four centimeters. 16 multiplied by four is equal to 64. And our units for area are square centimeters. The area of the rectangle is 64 square centimeters.
