Question

plz tell it solution​

Answer 1

Perimeter of Pentagon ABCDE = 5× side

=5×15

=75 cm

Area of a regular pentagon = pa/2,

where p = the perimeter and a = the apothem

P=75 cm

a= 10.32 cm

$area = \frac{75 \times 10.32}{2} \\ \\ = 387 \: {cm}^{2}$

Answer 2

$\huge{\sf{\mathcal{\fcolorbox{gold}{purple}{\underline{\underline{Answer ~♡~}}}}}}$

Perimeter of Pentagon ABCDE

= 5 × side

= 5 × 15

= 75 cm

Area of a regular pentagon

= (p × a)/2,

where p = the perimeter and a = the apothem

• P=75 cm

• a= 10.32 cm

$\\ \\ AREA = \frac{pa}{2} \\ \\ = \frac{75 \times 10.32}{2} \\ \\ = 75 \times 5.16 \\ \\ = 387$
