Find the area of the rectangle.
Hint:
 Hint:
 Area of rectangle is given by product of length and breadth.
 Area of rectangle = length × breadth.
 Area of rectangle = l × b
 Distributive property: a (b + c) = ab + ac
 Area of rectangle is given by product of length and breadth.
 Area of rectangle = length × breadth.
 Area of rectangle = l × b
 Distributive property: a (b + c) = ab + ac
The correct answer is: Hence, area of rectangle is 8x2 + 12x  8.
Answer:
Step by step explanation:

 Given:
 Length (l) = 2x + 4 unitsBreadth (b) = 4x  2 units
 Step 1:
 Find area of rectangle.So,
Area of rectangle = l × b
Area of rectangle = (2x + 4) × (4x  2)
 Step 1:
 Product of polynomials.
Area of rectangle = (2x + 4) × (4x  2)
Area of rectangle = 2x × (4x  2) + 4 × (4x  2)
[ a (b + c) = ab + ac ]
Area of rectangle = 8x^{2}  4x + 16x  8
Area of rectangle = 8x^{2} + 12x  8
 Final Answer:
Hence, area of rectangle is 8x^{2} + 12x  8.
 Given:
 Length (l) = 2x + 4 unitsBreadth (b) = 4x  2 units
 Step 1:
 Find area of rectangle.So,
Area of rectangle = l × b
Area of rectangle = (2x + 4) × (4x  2) Step 1:
 Product of polynomials.
Area of rectangle = 2x × (4x  2) + 4 × (4x  2)
[ a (b + c) = ab + ac ]
Area of rectangle = 8x^{2}  4x + 16x  8
Area of rectangle = 8x^{2} + 12x  8 Final Answer:
