Question
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 = 8x2 - 4x + 16x - 8
Area of rectangle = 8x2 + 12x - 8
- Final Answer:
Hence, area of rectangle is 8x2 + 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 = 8x2 - 4x + 16x - 8
Area of rectangle = 8x2 + 12x - 8- Final Answer:
