Answer:
9 units²
Step-by-step explanation:
This is a trapezium.
The length of the two parallel lines (on top and bottom) are 5 units and 1 units.
The height of the trapezium is 3 units. Using these information, we can apply the formula for area of trapezium to find the answer.
Area = 1/2 (5 + 1) x 3 = 9 units²
The two numbers are -18+ 2√(11) and -18 -2√(11).
-18+ 2√(11)+ [-18 -2√(11)]= -36
[-18+ 2√(11)]* [-18 -2√(11)]= 280.
Hope this helps~
B, 8 to 11 because general number of marbles is 8+3=11 and only 8 of all are white)
Answer:
0.5 ft^2
Step-by-step explanation:
The area in square inches is (6 in )(12 in) = 72 in^2.
Recall that 1 ft^2 = 144 in^2.
Then
72 in^2 1 ft^2
--------------- * --------------- = 0.5 ft^2
1 144 in^2
