What are the dimensions of the base? (answer)

Let width be x so length = 2x -65 perimeter = 2x + 2(2x-65) = 830 solve for x 2x + 4x - 130 = 830 6x = 960 x = 960/6 = 160 so width = 160 and length = 2x160 -65 = 255 :)

Let one number be x so other number must be x-3/4 x + x - 3/4 = 9 1/4 = 37/4 solve for x 2x = 37/4 + 3/4 = 40/4 x = 40/(2x4) = 40/8 = 5 so one number is 5 and other number is 5-3/4 = 4 1/4 :)...
