Answer:
72 square units
Step-by-step explanation:
The area is given by the formula ...
A = 1/2ab·sin(C)
A = 1/2(12)(24)sin(30°) = 1/2(12)(24)(1/2) = 72 . . . square units
So you have a base of 48 m (8*6) multiply that by the height(1/10m) you would get estimate 4.8 meters cubed. Since she has 5 meters cubed she will indeed have enough.
25 tens is the same as 250
