<em><u>The solution to the inequality is:</u></em>

<em><u>Solution:</u></em>
Given inequality is:

We have to find the solution to given inequality




Simplify the above inequality


Remember that, change the inequality sign if you divide or multiply both sides by a negative number
If you divide or multiply both sides by a positive number,the inequality sign will not change



Thus the solution to inequality is found
Answer:
64 + 64sqrt(3)
174.9 cm²
Step-by-step explanation:
AD/2 = 8cos(60) = 4
AD = 8 cm
Height of each triangle = 8sin(60)
= 4sqrt(3)
sqrt: square root
Area = 8² + 4(½ × 8 × 4sqrt(3))
= 64 + 64sqrt(3) cm²
= 174.8512517 cm²
For number 9 the answer is 35.
