Answer:
x² + 12x + 35
Step-by-step explanation:
The area of the blue section is x * x = x².
Pink: x * 7 = 7x
Green: x * 5 = 5x
Orange: 7 * 5 = 35
When we add these up we get x² + 12x + 35. Hope this helps!
Answer: x2 + 12x + 35
Area of a rectangle = l x w
A = (x + 7) (x + 5)
= x2 + 5x + 7x + 35
= x2 + 12x + 35
