13,822 to one significant figure is 10,000

623 to one significant figure is 600

14 to one significant figure is 10

10,000 times 600 = 6,000,000

6,000,000/10 = 600,000

<u>To find the area of a complex shape</u>:

⇒ must split into simpler shapes

a rectangle of <u>8m by 7m</u>
a rectangle of <u>2m by 8 m</u>

<u>Now let's find</u>:

Area of a rectangle of <u>8m by 7m</u>

$Area=8*7=56m^2$

Area of a rectangle of <u>2m by 8m</u>

$Area = 2 * 8 = 16m^2$

<u>Total Area</u> = 56 + 16 = <u>72 m²</u>

<u>Answer: 72 m²</u>

Hope that helps!
