\huge\text{Hey there!}


\huge\textbf{First thing, let's get the formula for}\\\huge\textbf{the regular pentagon/polygon.}


\mathbf{(1)/(2)* \boxed{a}pothem*\boxed{p}erimeter = {\boxed{a}rea}}


\huge\textbf{Or we could simply say....}


\mathbf{\frac{\boxed{n}umber\ of\ sides\ you\ have * \boxed{s}ide \ length\ on\ one\ side* \boxed{a}pothem}{2} = \boxed{a}rea}


\huge\textbf{Let's plug the pieces to the equation,}\\\huge\textbf{since we have that information out the}\\\huge\textbf{way.}


\bullet\mathbf{\ Number\ of\ sides \rightarrow \boxed{\bf 5}}


\bullet\mathbf{\ Side\ length\ of\ one\ side \rightarrow \boxed{\bf 6\ inches}}


\bullet\mathbf{\ Apothem \rightarrow \boxed{\bf 4\ inches}}


\huge\textbf{Making the equation for you:}


\mathbf{(5* 6 * 4)/(2) = \boxed{a}rea}


\huge\textbf{Solving for the result:}


\mathbf{(5* 6 * 4)/(2) = \boxed{a}rea}


\mathbf{(30* 4)/(2) = \boxed{a}rea}


\mathbf{(120)/(2) =\boxed{a}rea}


\mathbf{(120/2)/(2/2) = \boxed{a}rea}


\mathbf{(60)/(1) = \boxed{a}rea}


\mathbf{60/1 = \boxed{a}rea}


\mathbf{60 = \boxed{a}rea}


\huge\textbf{Met the result....}


\huge\text{Thus, your answer should be: \boxed{\mathsf{60\ in^2}}}\huge\checkmark


\huge\text{Good luck on your assingment \& enjoy your day!}

Answer:

60 in²

Explanation:

Area of a Regular Polygon


\textsf{A}=(n\:s\:a)/(2)

where:

  • A = area
  • n = number of sides
  • s = length of one side
  • a = apothem (the line drawn from the center of any polygon to the midpoint of one of the sides)

From inspection of the diagram:

  • n = 5
  • s = 6 in
  • a = 4 in

Substitute the values into the formula and solve for A:


\implies \sf A = (5 * 6 * 4)/(2)


\implies \sf A = (120)/(2)


\implies \sf A = 60\:in^2

Therefore, the area of the given regular pentagon IJKLM is 60 in².
