Answer:280
Step-by-step explanation:14 x 20 = 280
Answer:
235 cm
Step-by-step explanation:
First, find the area of the whole rectangle (bxh)
14x20=280
Next, find area of the missing piece
5x9=45 ( to find this, 14-9, times 20-11)
Finally, subtract the missing piece from the total rectangle
280-45=235
4x - 5y x=4 , y=10
= (4*4) - (5*10)
= -34

d e f
solution is b,e
