4153.5 $m^{2}$

Step-by-step explanation:

You can split this question into two distinct shapes

Rectangle:

Area of a rectangle = Height * Length

A = 25 * 87.6

A = 2190 $m^{2}$

Circle:

Both semi circles and be combined to make one full circle

Area of a circle = π $r^{2}$

A = π * $25^{2}$

A = 1963.5 $m^{2}$

Total Area:

2190 + 1963.5 = 4153.5 $m^{2}$
