Answer:
1120
Step-by-step explanation:
To find the area split the shape into two rectangles. Find the area of each and add the areas together.
One is 18 by 40 so the area is A = 18*40 = 720.
The other is 10 by 40 so the area is A = 10*40 = 400.
Together the area is 720 + 400 = 1120.

Answer:
<em>30 min</em>
<em></em>
Step-by-step explanation:
The tank can be filled in 15 min, this means that in one min, 1/15 of the tank can be filled.
The tank can be emptied in 10 min, this means that in one min, 1/10 of the tank can be emptied.
the outflow rate - the inflow rate = rate of emptying the tank
1/10 - 1/15 = 1/x
where x is the time it will take to empty the tank
solving, we'll have
1/30 = 1/x
the reciprocal of the equation gives
x = <em>30 min</em>
