If i want to compare the length of a shadow cast by a basketball goalpost 10ft with 2ft backboard shadow 69 inches to the shadow of the goalpost measured with a yardstick the shadow is 18inches and i get 3ft 6in for the goalpost & backboard can I say that the height of the basketball goals are similar or are they the same based on equal ratios?
