Answer:
4L +4W +16 square inches
Step-by-step explanation:
The area of the border is the equivalent of that of a rectangle with a width equal to the width of the border, and a length equal to the length of the midline of the border. That length is the perimeter of the rectangle that is L+2 units long and W+2 units wide.
border midline length = 2((L+2) +(W+2)) = 2L +2W +8
Then the border area is ...
border area = (border width)(border length) = (2)(2L +2W +8)
border area = 4L +4W +16 . . . square inches
_____
You can also figure this as the difference between the area of the rectangle with the border and the area of the rectangle inside the border:
border area = total area - canvas area
= (L+4)(W+4) -LW = LW +4L +4W +16 -LW
= 4L +4W +16 . . . . square inches

Answer:
1. 10
2. 4
3. 0.51
4. 2.67
5. 1.2
6. 0.5
Step-by-step explanation:
1. 3/8 + 2/8 = 5/8 = 0.625
0.625 * 16 = 10
2. 7 - 1 = 6
6 * 3 = 18
72/18 = 4
3. 1/12 = 0.08
4 * 0.08 = 0.32
5/6 = 0.83
0.83 - 0.32 = 0.51
4. 2.3 + 1.7 = 4
4 * 3 = 12
32/12 = 2.67
5. 6.3 - 5.1 = 1.2
0.7 + 0.3 = 1
1.2 * 1 = 1.2
6. 0.5 * 0.5 = 0.25
0.25/0.5 = 0.5
