The answer is the second choice, or B; 240 ft^2.
You have to find the area of all four triangles and just add those all together.
Two of the triangles have an area of
5*16=80
Multiply that by two
80*2=160
The other two smaller triangles have an area of
8*5=40
Multiply that by 2 also
40*2=80
Add 160+80 and the answer is 240.
Answer:
none of the options shown
Step-by-step explanation:
You can add 2x+2 to the inequality and get ...
8 ≥ 2x
4 ≥ x . . . . . divide by 2
This means that there should be a solid circle at x=4, and shading should be to the left of that.
None of the three graphs shown here is appropriate. (We don't see Option 2.)

Attached is the output of a graphing calculator. The solid line at x=4 corresponds to a filled dot on a number line plot.
Answer:
110 feet
Step-by-step explanation:
The formula to find the area of a rectangular prism is A = 2 (wl + hl + hw)
Substitute the values:
A = 2 (5x5 + 3x5 + 3x5)
A = 2 (25 + 15 + 15)
A = 2 (25 + 15 + 15)
A = 2 (55)
A = 110
