Question

Please help me....

Answer 1

Answer: 854 squared kilometres

2 ways u could do it:
45 x 24 = 1080
5 x 20 = 100
9+5=14
14x9 = 126
100+126=226
1080-226 = 854
I just worked out the total area of a whole rectangle then took away the missing parts

Or you could split it into different sections:
24x16=384
24-5=19
19x20=380
9x10=90
384+380+90=854
