Answer 1

The problem ask for the dimension of the  window if the ration between the two side is 1.7 is to 1 and the window has an area of 2,720 square inches and the side should be in letter D. 40 inches by 68 inches. I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

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
