Answer:

b = 10

Step-by-step explanation:

50 = 2 (15 + b)

multiply

50 = 30 + 2b

subtract

20 = 2b

divide

b = 10

<h3><u>G</u><u>i</u><u>v</u><u>e</u><u>n</u>:-</h3>

P = 2 (l + b) when l = 15 and P = 50

<h3><u>T</u><u>o</u><u> </u><u>F</u><u>i</u><u>n</u><u>d</u>:-</h3>

To find b

<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

P = 2 (l + b) [Given]

Putting the value of P = 50 and l = 15 we get,

50 = 2(15 + b)

\frac{50}{2} = 15 + b

25 = 15 + b

25 - 15 = b

10 = b

So, b = 10

<h3>Value of b is <u>1</u><u>0</u>. [Answer]</h3>

If you want the top 15%, the score corresponds to the 85th percentile. That score is 313.

The area is found by base x height

To find the missing height in the first one you divide 147 by 15 3/4 and get 9 1/3. 
To find the missing base in the second one you divide 140 5/8 by 11 1/4 and get 12 1/2.
To find the missing height in the third one you divide 151 3/16 by 10 1/4 and get 14 3/4.
