Answer:
x² + 11x + 28
Step-by-step explanation:
Length = 4 feet
Width = 7 feet
If it is increased by x feet
Length = 4 + x feet
Width = 7 + x feet
Area of the garden = length × width
= (7+x) × (4+x)
= 28 + 7x + 4x + x²
= x² + 11x + 28
The expression that could be used to calculate the area of the garden = x² + 11x + 28
