Calculate the perimeter and area of the following figures on page 97 (the last question) of the second volume of the sixth grade math book

I'm from PEP:

Circumference: 5× 3.14 ÷ 2 ~ 5× 2 ~ 3 ~ (5 ~ 3) =15 (m) Area: 5× 3 = 15 (m).

= 15.7÷2﹢5 15﹢ 12.85=27.85(m)= 2.5×3. 14÷2

=7.85﹢5 =7.85÷2

= 12.85 (m) =3.925 (m)

15﹢3.925= 18.925(m)
