Answer:
Perimeter = 2x² + 16x + 6
Area = 6 x² + ¹/₂x - 3
Step-by-step explanation:
The perimeter = a + b + c + d
= (6x + 4) + (2x² + 5x - 3) + (-3x - 6) + (8x + 11)
= 2x² + 16x + 6
The area = [(a + b) ÷ 2] h
= [((6x + 4) + (-3x - 6)) ÷ 2] (4x + 3)
= [(3x - 2) ÷ 2] (4x + 3)
= (³/₂x - 1) (4x + 3)
= 6 x² + ¹/₂x - 3
