The area of this rectangle is 96 ft2.
What is the length and width?

Answer:
length is 8
width is 12
Step-by-step explanation:
the equation to solve this would be
x*(x+4)=96
you isolate the variable by dividing each side by factors that doesn't contain the variable
X would then equal 8
length is 8
width is 8+4= 12
