Answer :
A. (i) Length of family room = 5.48 m
Breadth of family room = 4.57 m
Perimeter of family room = 2 (l + b) = 2 (5.48 + 4.57) = 2 × 10.05 = 20.1 m2
Moulding required for family room = 20.1 m2
(ii) Length of living room = 7.53 m
Breadth of living room = 3.81 m
Perimeter of living room = 2 (l + b) = 2 (7.53 + 3.81) = 2 × 11.84 = 22.68 m2
Moulding required for living room = 22.68 m2
(iii) Length of dining room = 5.48 m
Breadth of dining room = 5.41 m
Perimeter of dining room = 2 (l + b) = 2 (5.48 + 5.41) = 2 × 10.89 = 21.78 m2
Moulding required for dining room = 20.1 m2
(iv) Side of bedroom 1 = 3.04 m
Perimeter of bedroom 1 = 4 × side = 4 × 3.04 = 12.16 m2
Moulding required for bedroom 1 = 12.16 m2
(v) Length of bedroom 2 = 3.04 m
Breadth of bedroom 1 = 2.43 m
Perimeter of dining room = 2 (l + b) = 2 (3.04 + 2.43) = 2 × 5.47 = 10.94 m2
Moulding required for dining room = 20.1 m2
B. Area of family room = 5.48 × 4.57 = 25.0436 m2
Cost of carpeting family room at the rate of Rs 200/m2 = 200 × 25.0436 =Rs. 5008.72
Area of living room = 7.53 × 3.81= 28.6893 m2
Cost of carpeting living room at the rate of Rs 200/m2 = 200 × 28.6893 =Rs. 5737.86
Area of dining room = 5.48 × 5.41= 29.6468 m2
Cost of carpeting dining room at the rate of Rs 200/m2 = 200 × 29.6468 =Rs. 5929.36
Area of bedroom1 = 3.04 × 3.04 = 9.2416 m2
Cost of carpeting bedroom1 at the rate of Rs 200/m2 = 200 × 9.2416 =Rs. 1848.32
Area of bedroom2 = 3.04 × 2.43 = 7.3872 m2
Cost of carpeting bedroom 2 at the rate of Rs 200/m2 = 200 × 7.3872 =Rs. 1477.44
C. Total perimeter of all five rooms = 20.1 + 22.68 + 21.78 + 12.16 + 10.94 = 87.66 m
Cost of moulding 1 m = Rs 500
Total cost of moulding all five rooms = 500 × 87.66 = Rs. 43,830
