r1 = 14 cm, r2 = 3.5 cm, l = 3 cm, b = 1 cm
area remaining = original area - area of 2 circles - area of rectangle
= πr1² - 2πr2² - l*b
= 22/7 * 14² - 2 * 22/7 * 3.5² - 3*1
= 616 - 77 - 3
= 536 cm²
area remaining = original area - area of 2 circles - area of rectangle

= 22/7 * 14² - 2 * 22/7 * 3.5² - 3*1
