Area of the shaded portion = 1664 m$^{2}$
To find the area of the shaded portion we simply find the area of the entire rectangle and subtract the area of the un-shaded triangle. Area of a Rectangle: $A$$_{rect} = l$$w$ Therefore: $A$$_{rect} = (52 m)(37 m) A$$_{rect}$ = 1924 m$^{2}$ Area of a Triangle: $A$$_{tri} = \frac{1}{2}$$b$$h Therefore: A$$_{tri}$ = $\frac{1}{2}$(52 m)(10 m) $A$$_{tri} = 260 m^{2} A$$_{total}$ = $A$$_{rect} - A$$_{tri}$ Therefore: $A$$_{total}$ = 1924 m$^{2}$ - 260 m$^{2}$ = 1664 m$^{2}$
