Subtract the area of the (presumed) circular piece from the area of the square piece from which it is cut. This difference is what is left over. What do you find?

The circle has a radius of $\displaystyle 0.9\text{ m.}$

Its area is:.$\displaystyle \pi(0.9^2) \,=\,0.81\pi\text{ m}^2$

The waste (shaded area) is:.$\displaystyle 4 - 0.81\pi\text{ m}^2$
