"STANDARD" CITY BLOCK. Many urban areas have regularly sized blocks.

mate is an uphill or downhill one, and the solution comes from a Greek mathematician named Pythagoras. He discovered that you could exactly compute the side of a triangle opposite a right angle by squaring the other two sides, which yielded the square of the third side. Confused? Look at our illustration.

The Pythagorean theoremâ€”A squared plus B squared equals C squaredâ€”requires that you square A, which is the desired height above ground, then add it to the square of B, which is the distance to the house. Take the result and determine its square and you'll have the distance for C. Let's try it once.

The building is 100 feet tall, which we'll convert to 33.3 yards, and multiple it by itself to equal 1,108.89. Now, the distance from the building base to the house is 175 yards, which times itself is 30,625. Combining A and B, (1108.89 + 30,625) equals 31,733.89, and to find C we find it's square. Thus, C is 178.1 yards.
