Perimeter:
Area:​

Answer 1

Perimeter = 40 cm

Area = 52 cm²

Step-by-step explanation:

Perimeter = sum of all sides

= 8 cm + 3 cm + 5 cm +6 cm +2 cm + 5cm +11 cm

= 40 cm

area = f¹ area + f² area + f³ area

f¹ area = area of a 5 cm × 3 cm rectangle

= 5 cm × 3 cm

= 15 cm²

f² area = area of a 9 cm × 3 cm rectangle

= 9 cm×3 cm

= 27 cm²

f³ area = area of a 2 cm × 5 cm rectangle

= 2 cm × 5 cm

= 10 cm²

area of total figure = f¹ area + f² area + f³ area

= 15 cm² + 27 cm² + 10 cm²

= 52 cm²

hope it helps.
