2. Area of parallelogram = base*height
A = 24*9
A = 216
3. Surface area of prism = 2(wl + hl + hw)
l = 15 , w = 3 and h = 4
2(3*15+4*15+4*3)
2(45+60+12)
2(117)
234
Surface area of rectangular prism is 234mm^2

Depends on the question...

If your question is 2/3b + 5 = 7, then follow this one
$\frac{2}{3}b + 5 = 7\\\\\sf You~ first~subtract~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b + 5 - 5 = 7 - 5\\\\\frac{2}{3}b = 2\\\\\frac{2}{3}b \times \frac{3}{2} = 2 \times \frac{3}{2}\\\\b = 3$
Your final answer will be b = 3

If your question is 2/3b - 5 = 7, then follow this one
$\frac{2}{3}b - 5 = 7\\\\\sf You~ first~add~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b - 5 + 5 = 7+5 \\\\\frac{2}{3}b = 12\\\\\frac{2}{3}b \times \frac{3}{2} = 12 \times \frac{3}{2}\\\\b =18$
Your final answer will be b = 18

Step-by-step explanation:

Take the natural log of both sides:

$ln ({x}^{y} ) = ln ({y}^{x} )$
