This is one of the easiest ways to get the answer
1.981: One and nine hundred eighty-one thousandths
Answer:
Length = 15
Width = 6
Area = 90
Step-by-step explanation:
Area of the rectangle = 
Lets factorise the polynomial


We know that Area = Length × Width
Let the length be (x + 3) & width be (x - 6)
Its given in the question that x = 12. So putting the value of x gives ,
Length = 
Width = 
Area = Length × Width = 15 × 6 = 90
Im pretty sure you put the wrong picture. The slope isn't negative and there is no point O,A, or B.
