A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be made measures 7 cm.7 cm. The longest side of the drawing measures 20 cm.20 cm. The longest side of the actual triangular piece to be sculpted must be 10.6 m10.6 m long. How long will the shortest side of this piece be?
Convert m to cm
10.6m = 1060 cm
So....we have the following proportion
Shortest side of actual piece Shortest side of model piece
---------------------------------------- = ---------------------------------------
Longest side of actual piece Longest side of model piece
Shortest side of actual piece 7cm
________________________ = _______
1060 cm 20 cm
Multiply both sides by 1060
Shortest side of actual piece = 7 * 1060 / 20 = 371 cm
