Joe purchased 56 feet of material to fence in his rectangular garden. The length of the garden must be 21 feet. Given the total amount of fencing material that Joe could use

The width of the garden must be 7 feet.

Step-by-step explanation:

Total amount of fencing material = 56 feet, and given that the length of the garden = 21 feet.

Since the fence would be in the shape of a rectangle, then;

perimeter of a rectangle = 2(l + w)

where l is the length and w is the width.

So that, perimeter = 56 feet, l = 21 feet.

Thus,

56 = 2(21 + w)

28 = 21 + w

w = 28 - 21

  = 7

The width of the garden must be 7 feet.

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
