Calculate the area of the regular pentagon below: A regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.

238.95 in²

because this is a regular pentagon

=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.

we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)

=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)

Step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
