A span on a bridge is the distance between supports such as from pier to pier. A bridge can have several supports over its length. A bridge length includes the entire bridge.

###### Asked in Tower Bridge (London)

### Is the tower bridge the same as the London bridge?

Absolutely not! London Bridge is an ordinary modern (1973)
bridge which spans the river Thames. Its predecessor, built in
1820, is now located at Lake Havasu in Arizona. Tower Bridge,
completed in 1894, also spans the river Thames and is the only
bridge across the Thames which can be raised to allow large ships
to pass underneath it, although that doesn't happen very often now.
The original Victorian mechanism can still be seen in working
condition in the bridge's museum. The bridge is quite distinctive,
with two tall towers at each end and is situated next to the Tower
of London from where it got its name.
No. They are two separate and very different bridges. Foreigners
often think that Tower Bridge is London Bridge, but they are very
wrong.

### What is length of each side of the isosceles trapezoid if the perimeter equal 119?

Several solutions are possible here. The four sides could be the
same length, or different lengths. The only requirement (with
respect to lengths) to be called an "isosceles trapezoid" is that
two opposite sides have the same length.
