Question

3.)The area of a regular polygon is 145.8 sq. cm. If the perimeter of this polygon is 108 cm,find the length of the apothem.

Answer 1

The area of the regular polygon is a= 145.8 sq.cm

Perimeter of the polygon is p=108 cm.

Let apothem length be a

We know,

a=p x a/2

Putting the values,

145.8=108xa/2

a=2.7 cm

The length of the apothem is 2.7 cm
