Step-by-step explanation:Area of quadrilateral =sum of area of two triangles form by the diagonal

Suppose the diagonal as base we have height of the formed triangles

[tex]area = \frac{1}{2} \times 18 \times 12 + \frac{1}{2} \times 18 \times 14[/tex]

[tex] = 108 + 126 = 234[/tex]

Cost of landscaping =234×5=₹1270
