We know that :

⊕ Sum of the interior angles in a Pentagon should be equal to 540°

⇒ x° + (2x)° + (2x)° + 90° + 90° = 540°

⇒ (5x)° = 540° - 180°

⇒ (5x)° = 360°

$\sf{\implies x^{\circ} = \dfrac{360^{\circ}}{5}}$

⇒ x° = 72°

Answer: 21.994 cm²

Step-by-step explanation:

Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.

Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142

Now area of the bigger circle = 3.142 x 3²

= 3.142 x 9

= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2

= 6.284 cm².

Therefore are of the shaded region = 28.278 - 6.284

= 21.994 cm²

It’s already in standard form: 93,000,000

If we would put it in scientific notation though, it would be: 9.3 x10 ^7 (to the power of 7)
