Question

Harry created a canvas painting on a square canvas. He then placed an order for a new rectangular canvas. The side length of the old square canvas is x inches. The new canvas he ordered has the same length, but a width 8 inches greater than that of the old canvas. The area of the new canvas is given by the quadratic expression below, where x represents the side length, in inches, of the old canvas.

Answer 1

Old canvas = x times x =100 inches

New canvas = X times 18= 180 inches

Answer 2

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

`=x * (x+8)\\\\=x^2+8x` square inches
