Perimeter = $13 \frac{1}{2}$ $13 1/2$ feet

There are two important words in the information given.

It is a regular figure, which means all the sides and angles are equal.

It is a hexagon, which means there are 6 sides.

So, there are 6 sides, each of length $2 \frac{1}{4}$ $2 1/4$ feet.

Simply multiply to find the perimeter. (the sum of all the sides)

$P = 6 \times 2 \frac{1}{4}$ $P = 6 xx 2 1/4$

$6 xx 9/4 = cancel6^3 xx 9/cancel4^2 = 27/2$

Perimeter = $13 1/2$ feet
