Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

Use 3.1 < sqrt 10 <3.2 to find the possible values of each expression. 2+sqrt 10
lilavasa [31]

The inequality which represents possible values of the expression 2+sqrt 10 by virtue of the given inequality; 3.1 < sqrt 10 < 3.2 as in the task content is; 5.1 < 2 + sqrt 10 < 5.2.

<h3>Which inequality correctly expresses the possible values of the expression; 2 + √10 as required in the task content?</h3>

It follows from the task content that the expression given is;

3.1 < sqrt 10 < 3.2

Since the given premises is an inequality, it follows that adding the same number to all parts of the inequality stills holds the inequality true.

Hence by adding 2 to all parts of the inequality, we have;

2 + 3.1 < 2 + sqrt 10 < 2 + 3.2

Therefore, we have;

5.1 < 2 + sqrt 10 < 5.2

Ultimately, 5.1 < 2 + sqrt 10 < 5.2 represent the possible values of the expression 2+sqrt 10 as given by the inequality 3.1 < sqrt 10 < 3.2.
