The shape can be split into 3 shapes
Triangle
Large rectangle
Small rectangle
Triangle area
A=1/2 bh
A=1/2 5(8)
A=20
Large rectangle
A=bh
A=16(8)
A=128
Small rectangle
A=bh
A=5(6)
A=30
Total area
20+128+30=178
The area of the shape is 178m^2
5 offices = x offices
6 hours 12 hours
quick math shows that it's 10 offices
Answer:
The new area of the similar figure would actually be 256 square centimeters. Want to know why it would by 256 and not 128 like you think and like the other answer says? That is because they are not saying the area is being doubled they are saying that the SIDES are being doubled. Therefore if the area was 64 then one side was 8. If you double 8 it is 16. Then the area of the new figure would be 16*16 or 16 squared which equals to 256 centimeters squared.
I luv you all XOXO
13,907 is going to be your answer since we do 12000 + 8000 + 1000 + 400 (1400) + 7, which gives you 13,907 for the answer.
Hope this helped!

The answer you seek is 15 and -4. 15*-4=-60 and 15-4=11.
