Answer 1

Answer:

The area of the cloth material wasted is 1.02 m²

Step-by-step explanation:

Diameter of the finished cloth = 1.2 m

allowance for hem = 5 cm = 0.05 m

Total diameter of cloth required to make the table cover = 1.2 + 0.05 = 1.25 m

Area of the table cover = π × (1.25²/4)

                                      = 1.23 m²

Area of the square piece cloth = 1.5 × 1.5 = 2.25 m²

Material wasted = 2.25 - 1.23 = 1.02 m²

Therefore, The area of the cloth material wasted is 1.02 m²

Hope this helps.
