➷ To work it out, you need to know this formula:
area of trapezoid =
'a' is the top side
'b' is the bottom side
'h' is the vertical height
Substitute the values in:
area =
Now solve:
area =
In short, your answer is B.

Answer:
m=1/300 du
Step-by-step explanation:
we have that m=∫∫rho(x,y)dA for this we must find the limits of integration (according to the graph1)
On the x axis: if y=2x and x+2y=1 then y=2x and y=(1-x)/2 ⇒ 2x=(1-x)/2 ⇒ 4x=1-x ⇒ 5x=1 ⇒ x=1/5; on the y axis y=0 and y=1/2
m=∫∫rho(x,y)dA (view the graph 2)
