follow the attached image and pls mark me brainliest

Answer 2

Step-by-step explanation:

(a) perimeter of whole part = 4+3+4+3 = 14 cm

perimeter of whole part = 2+1+2+1 = 6 cm

Perimeter of the shaded part to that of the whole figure = 6: 14 =3 : 7

(b) Area of the shaded figure = 2x 1 =2 cm^2

area of the whole figure = 4x 3 = 12 cm^2

ratio of area of the shaded figure to the area of the whole figure= 2 :12 =1:6
