Question

find the area of regular pentagon in which each side is 5cm and apothem is 6cm.

Answer 1

Answer:Given,

s = 5 cm

a = 6cm

Area of a pentagon= 5/2 s*a

= 5/2 * 5 * 6cm²

= 75cm²

Answer 2

The area of regular pentagon $=75cm^{2}$

Step-by-step explanation:

We have,

The side of regular polygon(a) = 5 cm and

The apothem of regular polygon(s) = 6 cm

To find, the area of regular pentagon = ?

We know that,

Area of a pentagon= $\dfrac{5}{2} \times s \times a$

$= \dfrac{5}{2} \times 5 \times 6cm^2$

$= 5 \times 5 \times 3cm^2$

$=75cm^{2}$

Hence, the area of regular pentagon $=75cm^{2}$
