Answer
$4326\ m^2$
Work Step by Step
Working from the top down, the sketch can be divided into 6 rectangular sections. Find the area of each, and add them to find the total area.
$A_1=bh=(14)(10)=140$
$A_2=bh=(25)(22)=550$
$A_3=bh=(46)(16)=736$
$A_4=bh=(25)(12)=300$
$A_5=bh=(65)(20)=1300$
$A_6=bh=(25)(52)=1300$
Area Addition Postulate
$A=A_1+A_2+A_3+A_4+A_5+A_6=140+550+736+300+1300+1300=4326$
