Answer:

Step-by-step explanation:
The given expression is

We group the constant terms on the right hand side to obtain;


We square both sides of the equation to remove the square root.


This will simplify to;



A. Area of given figure = 280 + 77 = 357 cm²
B. length of semicircle = 22 cm
315 m²
<u><em>area of rec + area of rec + area of rec + area of triangle</em></u>
⇒ length + width + length + width + length + width + 1/2 * base * height
⇒ 19 * 6 + 9 * 9 + 18 * 5 + 1/2 * 12 * 5
⇒ 90 + 30 + 81 + 114
⇒ 315 m²
