Step-by-step explanation:
The width of border is 1.5 feet
<h3><u>
Solution:</u></h3>
Given that small garden measures 9 ft by 13 ft
A uniform border around the garden increases the total area to 192 ft square
To find: width of border
Let the width of border be "x"
Then the new measures of garden are (9 + 2x) feet and (13 + 2x) feet
The total area of garden = 192 square feet


<em><u>Let us solve the above equation by quadratic formula</u></em>

Using the above formula,
For
, we have a = 4 ; b = 44 ; c = -75
Substituting the values of a = 4 ; b = 44 ; c = -75 in above quadratic formula we get,


Since "x" cannot be negative,
we get x = 1.5
Thus width of border is 1.5 feet
3. 6/8/10 is twice the common Pythagorean Triple 3/4/5.
Answer: A. 10
