If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
Answer:
Step-by-step explanation:
7g = x miles
7 grade is x miles
8g = 7g + 15%
8 grad is 15% more than 7 grade
put what 7g is equal to into the 8g equation
8g = x + 15%

Answer: You would tell him 1,425ft².
Step-by-step explanation:

First, you need to know the equation for finding the area of a trapezoid, which is <em><u>½</u></em><em><u>h</u></em><em><u>(</u></em><em><u>b1</u></em><em><u>+</u></em><em><u>b2</u></em><em><u>)</u></em> .
When you plug in all the number you have into the equation, you have a new equation essentially that says, <em><u>½×30(65+50)</u></em> .
When you start solving the equation, you need to do parentheses first, so <em><u>65+30</u></em>, which would get you 95. This would then turn the equation into <em><u>½×30(95)</u></em> .
Next, you have to do <em><u>30×95</u></em>, which would come out to be 2850. When you do this, your equation would now be <em><u>½</u></em><em><u>×</u></em><em><u>2</u></em><em><u>8</u></em><em><u>5</u></em><em><u>0</u></em> , or essentially <em><u>2850</u></em><em><u>÷</u></em><em><u>2</u></em> .
When you do the last and final step of the problem, which is <em><u>½×2850</u></em>, you would get 1425. But since it's area, your answer would <em><u>1425ft²</u></em>.
