Option 1 : 1914 sq.m

**Given:**

Circumference of base = 132 m

Height = 20 m

**Concept:**

The area of the canvas required to make a tent is equal to the C.S.A of the cone.

**Formula used:**

C.S.A of cone = πrl

Circumference of circle = 2πr

**Calculation:**

2 × 22/7 × r = 132

⇒ r = (132 × 7)/(2 × 22) = 21 cm

h = 20 cm

l = √ 20^{2} + 21^{2}

l = 29 cm

C.S.A = 22/7 × 21 × 29 = 1914 sq.m

**∴ The area is 1914 sq.m**
