Aregular pentagon has an apothem measuring 3 cm and a perimeter of 21.8 cm.
what is the area of the pentagon, rounded to the nearest tenth?

area = 32.7 cm²

Step-by-step explanation:

The area (A) of a regular pentagon is

A = 0.5 × perimeter × apothem

  = 0.5 × 21.8 × 3 = 32.7

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
