The lengths of the sides of a rectangular window have the ratio of 1:6:1 the area of the window is 2822.4in^2 what are the windows dimensions

Let the width be x and the length = 1.7x

Area = length x width = x * 1.7x = 1.7x^2 = 2,720

x^2 = 2,720 / 1.7 = 1,600

x = sqrt (1,600) = 40

1.7x = 1.7 x 40 = 68

Therefore, the dimensions are 40 inches by 68 inches
