Perimeter is when you add up all the sides of a shape. For Anthony's shape, it would be 6 time 5, or 30 inches. For Carol's shape, it would be 6 times 5, or 30. Both shapes have the same perimeter. Hopefully this helps, let me know if you have any more questions.
Answer:
(a) 412 +A -B
(b) 412 +A -B + (A-20) -(B+14)
(c) 378 +2A -2B
Step-by-step explanation:
Water flowing in adds to the amount in the reservoir. Water flowing out subtracts from the amount in the reservoir.
__
(a) 412 + A - B . . . . at the end of January
__
(b) Flowing in was (A -20), flowing out was (B +14). In February, we start with the amount at the end of January.
(412 +A -B) +(A-20) -(B +14)
__
(c) Simplifying the above, we have ...
412 -20 -14 +2A -2B = 378 +2A -2B
Answer:
112 ft.
Step-by-step explanation:
This shape is a trapezoid. To find the area of a trapezoid, use the formula: 
. First find base one. The shape in the middle is a square, so the top side of the trapezoid will be worth 8 ft as well. Now add the two bases 8 + 20 to get 28 and then divide by 2 to get 14. Now multiply 14 by the height (8). 14 x 8 is 112 ft.
Hope it helps and is correct!
