450 square feet is a rectangular rectangle with a length of 45 feet and a width of 10 feet. The length and width of a rectangular rectangle are multiplied to get the square footage.
To keep the space at 450 square feet, the length would have to be expanded while the width would have to be reduced. To occupy 450 square feet, a rectangular space with a length of only 25 feet must be 18 feet wide. A 450-square-foot room does not have to be rectangular, but the square footage of circular, trapezoidal, and triangular spaces must be calculated using other geometric methods.
