A company makes picture frames for different sized pictures. A customer has several rectangular-shaped photographs that he wants framed. All of the photographs measure 10% inches for the width but vary in the length
The manager at the frame shop knows she can use the formula for perimeter. P = 21+ 2w. to determine the amount of wood that she'll need for each photograph.
One of the photos is 15 inches long. How much wood is needed for the frame? Type you answer as a decimal, not a fraction

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
