Question

Builders have observed that residence windows are most attractive if they have the width to length ratio 3:5. if a window is to be 48 inches wide, what should it's length be for the most attractive appearance?

Answer 1

Most attractive . . . width / length = 3:5 = 0.6

If width = 48 inches, then 48/length = 0.6

Multiply each side by 'length': 48 = 0.6 length

Divide each side by 0.6 : length = 48/0.6 = 80 inches
