Area: 120 ft. Quantity: 1<span />
Answer:
<h2><u><em>
x=3 or x=−4</em></u></h2>
Step-by-step explanation:
when a number x is added to it's square, the total is 12. find two possible values of x
x+x^2=12
x^2+x=12
x^2+x−12=12−12
x^2+x−12=0
(x−3)(x+4)=0
x−3=0 or x+4=0
x=3 or x=−4
x=3 or x=−4
We are given vertices of a rectangle (0, −4) , (−1, −3) , (2, 0) , and (3, −1).
Length is the distance between (0, −4) and (−1, −3) points.
Width is distance between (−1, −3) and (2, 0) points.
<u>Computing length:</u>



<u>Computing Width :</u>



<h3>
Area of the rectangle = Length × Width </h3>
