The ratio of a side length of rectangle A to a corresponding side length of rectangle B is 12: 5. Rectangle A has a side length of 60 inches. Find the corresponding side length of rectangle B. 38 n/(5 deg) 12/5 = 60/x 2x = 300 x = 25in X 8. The ratio of a side length of triangle A to a corresponding side length of triangle B is 5:8. Triangle A has a side length of 18 centimeters. Find the corresponding side length of triangle B. 18cmx 5/8 18/x = 5/8 5x = 144 x = 28.8cm 9. A farmer who is 72 inches tall is standing beside a silo that has a height of 140 feet. The length of the silo's shadow is 31.5 feet. What is the length of the farmer's shadow? 140/31.5 = 72/x 140x = 2268 x = 16.2ft 140 ft OR 140/72 = 3L5 x 140x = 2268 x = 16.2ft 31.5 ft 72 in. (Not druva to scale) OR 31.5/x = 140/72 OR 31.5/140 = x/72 Farmer's Shadow is 16.2 ft 80 Pre-Algebra
