Question
Find the area of the green rectangle.
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
The correct answer is: Hence, area of green rectangle is 10x2 + 24x + 8.
Answer:
Step by step explanation:
- Given:
Length (l) = 5x + 2 units
Breadth (b) = 2x + 4 units
- Step 1:
- Find area of green rectangle.
So,
Area of rectangle = l × b
Area of rectangle = (5x + 2) × (2x + 4)
- Step 2:
- Product of polynomials.
Area of rectangle = (5x + 2) × (2x + 4)
Area of rectangle = 5x × (2x + 4) + 2 × (2x + 4)
[ a (b + c) = ab + ac ]
Area of rectangle = 10x2 + 20x + 4x + 8
Area of rectangle = 10x2 + 24x + 8
- Final Answer:
Hence, area of green rectangle is 10x2 + 24x + 8.
