If you know your multiplication tables it becomes quite simple to find the area of a rectangle. You can round your lengths up or down accordingly to find the area of a figure. For example, what if we had a square 2.334" by 3.574"? The 2.334 rounds down to 2 and the 3.574 rounds up to 4. Now we have a 2 by 4" rectangle. Now we find our area. 2*4=8 inches squared. Does that answer your question?

Answer:

Step-by-step explanation:

$3 {(x + 9)}^{ \frac{3}{4} } = 24 \\ \\ {(x + 9)}^{ \frac{3}{4} } = \frac{24}{3} \\ \\ {(x + 9)}^{ \frac{3}{4} } = 8 \\ \\ {(x + 9)}^{ \frac{3}{4} } = {2}^{3} \\ \\ (x + 9) = {2}^{3 \times \frac{4}{3} } \\ \\ x + 9 = {2}^{4} \\ \\ x + 9 = 16 \\ \\ x = 16 - 9 \\ \\ x = 7$
