Old canvas = x times x =100 inches

New canvas = X times 18= 180 inches

Answer:

Side length of the old square canvas = x inches

Area of old canavas which is in the shape of Square

                                                     = (Side)²

                                                     =x² square inches

Length of new rectangular Canavas=x inches

Breadth of new rectangular Canvas=(x+8) inches

Area of Rectangle(Area of the new canvas)=Length × Breadth

                [tex]=x \times (x+8)\\\\=x^2+8x[/tex]  square inches
