Answer:

60 sq in

Step-by-step explanation:

The appropriate formula is ...

... A = (1/2)Pa . . . . . where P is the perimeter and "a" is the apothem

The figure has 5 equal-length sides of 6 inches, so its perimeter is ...

... P = 5 × 6 in = 30 in

... A = (1/2)(30 in)(4 in) = 60 in²

The area is 60 square inches.
