Each of the side chambers of the Lincoln Memorial are 38 feet wide and 63 feet long. What is the perimeter of one of the side chambers?

Hello Zoe,

A regular hexagon has six equal sides. If the perimeter of the regular hexagon is 42 yards, then the length of each side would be one sixth of the perimeter, or 7 yards.

A rectangle, having a length $L$ and a width $W$ has a perimeter $P$ that is made up of two sides of measure $W$ and two sides of measure $L$, that is:

$P=2W+2L=2(W+L)$

The rectangular side-chambers of the Lincoln Memorial, whose measures are given as:

$W=38\text{ ft}$

$L=63\text{ ft}$

would then have a perimeter equal to:

$P=2(38\text{ ft}+63\text{ ft})=202\text{ ft}$

$P=2(38\text{ ft}+62\text{ ft})=202\text{ ft}$

Another of your typos there, Mark? (Smirk) (Shake)
