Answer:Assuming thickness of original plate and scale to be same.
Area of plate = 1120000mm
Sqr = area of scale
Actually volume shoud be equated but thickness is same.
Therefore area can be equated.
Area of scale = a × 20a
= 20a²
= 1120000mm²
a² = 56000
a = 236.64
Dimension = a × 20 a
= 236.64 × 1433.8
