Rectangle ABCD has vertices at A (-1, 1), B (2, 1), C (2, -5), and D (-1, -5). What is the perimeter of rectangle ABCD?

Solution:

The perimeter of rectangle is:

Perimeter = 2( length + width)

Rectangle ABCD has vertices at A (-1, 1), B (2, 1), C (2, -5), and D (-1, -5)

Let AB be the length

Let BC be the width

Find distance between A and B

The distance between two points is given as:

Therefore,

Thus, AB = length = 3 units

Find the distance between B and C

Therefore,

Thus width = 6 units

Therefore,

Perimeter = 2(3+6) = 2(9) = 18

Thus perimeter of rectangle is 18 units

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
