Question

Find the perimeter of the following quadrilateral.The bottom side measures 2 ft.

Answer 1

The perimeter of a quadrilateral is given by the sum of all the sides.

In order to add mixed numbers, let's rewrite them as a sum of the integer part and the fraction part.

So we have:

`\begin{gathered} P=1(5)/(12)+3(3)/(4)+2(1)/(6)+2 \\ P=1+(5)/(12)+3+(3)/(4)+2+(1)/(6)+2 \\ P=(1+3+2+2)+((5)/(12)+(9)/(12)+(2)/(12)) \\ P=8+(16)/(12) \\ P=8+1+(4)/(12) \\ P=9+(1)/(3) \\ P=9(1)/(3)\text{ ft} \end{gathered}`

Therefore the perimeter is 9 1/3 ft.
