If I have a 20m x 20m quadrat can this be expressed as 20m²

and if I have 50 quadrats at 20m x 20m how can this be expressed in its simplest form

it might sound basic but I'd need to be sure....

Cheers

A 20m x 20m quadrant is 400m^2. (Area is length*length for a square)

You have 50 of these quadrants so to find the total area multiply 50 by 400m²: $A = 400 \times 50 = 20000 \text{ m}^2 = 2 \times 10^4 \text{ m}^2$
