Question

The blueprint of a triangular patio has side lengths 4.5 in., 4.5 in., and 6.75 in. If the shorter sides of the actual patio are each 22.5 ft long, how long is the third side?

Answer 1

The blueprint of the patio is a scaled-down version of the actual patio. The scale factor between the blueprint and the actual patio is 22.5 ft / 4.5 in = 5 ft/in. Therefore, the third side of the actual patio is 6.75 in × 5 ft/in = 33.75 ft long.
