Question

find the area and perimeter of the shaded part in each of the following figures​

Answer 1

Answer:

Perimeter: ( Add all the sides and you will get the answer)

∴ 15+5+8+8+(15+8+8)+2+8+8+5+3+15+3 = 111

Area: (Multiply length and width) There are 3 rectangles intersecting each other - just to make you understand

∴ (15X3) X (5X10) X (2X20) = 90,000

Step-by-step explanation:

Perimeter - Just added all the sides

Area - Multiplied length and width

Answer 2

Answer:

Perimeter = 88m

Area = 127m²

Step-by-step explanation:

Perimeter :-

15 + 3m + 3m + 5m + 5m + 8m + 8m + 8m + 8m + 2m + 2m + 21m = 88m

Area :-

a = l × b

= 15 × 3

= 45 m²

b = 8 × 5

= 40 m²

c = 21 × 2

= 42 m²

Total area = (45+40+42)m²

= 127m²
