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
Answer:
x = 6
y = 8
