Answer:
263(usually it would say cm or m)²
Explanation:
area = l x w
l= 25
w= 19
25 x 19 = 551
thats the area without subtracting the missing area's.
missing area= 9 x 16
=144
since theres 2 areas missing, times it by two
144 x 2
=288
subtract the missing area from the total because its not there.
551 - 288
= 263
