paula casts two shadows 2 meters long at the same time a tree casts a shadow 28 meters long.The tree is 17.5 meters tall.How tall is paula?
We can solve this with a proportion....we have
17.5 / 28 = P / 2 where P = Paula's height ......cross-multiply
2(17.5) = 28P divide both sides by 28
[2 * 17.5] / 28 = P = 5/4 m = 1.25m
