Answer:
31x + 55 sq. ft.
Step-by-step explanation:
Width of Fire Pit = x ft. Length of Fire Pit = 4x ft.
Width of Patio = x + 5 ft. Length of Patio = 4x + 11 ft. Area of Fire pit = 4x * x = 4x² sq, ft.
Total Area of Rectangular Patio (including Fire pit) = (4x + 11)(x+5)
= 4x² + 31x + 55 sq. ft.
Area for which tiling is done = Area of Rectangular patio - Area of fire pit
= 4x² + 31x + 55 - 4x²
= 31x + 55 sq. ft.
