Question 1: The formula to calculate the perimeter of the banner is :-

(a) 2 (l + b)

(b) 2πrh + 2πr2

(c) πr + (2l + b)

(d) 2 (l + b) + πr2

Answer :-

→ perimeter of semi - circle + perimeter of 3 sides of rectangle

→ (2πr/2) + (2l + b)

πr + (2l + b) (c) (Ans.)

Question 2) :- The total surface area of the banner is

(a) 55860 cm2

(b) 70952 cm2

(c) 55880 cm2

(d) 70558 cm2

Answer :-

→ TSA = Rectangle area + (1/2)πr²

→ TSA = (208 * 96) + (1/2) * (22/7) * (98)²

→ TSA = 40768 + 22 * 49 * 14

→ TSA = 40768 + 15092

→ TSA = 55860 cm² (a) (Ans.)
