<h2>Answer:</h2>

The percent of the volunteers who were at least 15 years old but no more than 24 years old are:

                            30%

<h2>Step-by-step explanation:</h2>

We will make a table based on the histogram:

    Age-group            Number of students

       10-14                               3

       15-19                                2

       20-24                              7

       25-29                              8

       30-34                              5

       35-39                              5

Hence, the number of volunteers who are atleast 15 years no more than 24 years old are those who come in the age-group 15-19 and 20-24.

Hence, total number of such students= 2+7=9

and the total number of students= 3+2+7+8+5+5= 30

Hence, the percent of volunteers who lie between 15-24 years of age are:

=\dfrac{9}{30}\times 100\\\\=30\%

                    Hence, the answer is: 30%

Answer:

Length of rectangle = 16 cm

Width of rectangle = 4 cm

Step-by-step explanation:

Given:

Area of rectangle = 64 cm²

Find:

Length and width

Computation:

Assume;

Length of rectangle = a

So,

Width of rectangle = a -12

Area of rectangle = l x b

So,

a(a-12) = 64

a² - 12a - 64 = 0

a² - (16-4)a - 64 = 0

a² - 16a+ 4a - 64 = 0

a (a-16) + 4(a-16)= 0

(a-16)(a+4) = 0

a= 16 , a = -4

So,

Length of rectangle = 16 cm

Width of rectangle = a -12

Width of rectangle = 16 -12

Width of rectangle = 4 cm
