​

Answer 1

$\bf\large\underline\pink{Answer:-}$

Meena is not right as Area of Track is 3066 m²

Step-by-step explanation:

Figure is attached

Area of Track = 2 * (Rectangular area + Semicircular Area)

Rectangular area = 120 * 7 = 840 m²

Larger radius of Circle = 70/2 = 35 cm

Smaller radius of Circle = 35 - 7 = 28 m

Area of Semi circle = (1/2) π (35² - 28²)

= (1/2)(22/7) ( 63 * 7)

= 11 * 63

= 693 m²

Area of Track = 2 * (840 + 693)

= 2 * (1533)

= 3066 m²

Area of Track = 3006 m²

Meena is not right.
