1. Of the choices given 200 km is a reasonable distance for cities to be separated. 200 mm is about the size of a toddler's first step.
2. The answer is A if those are commas.
3.
P = 2*L + 2*W
P = 2*97 + 2*17
P = 194 + 34
P = 228

The area of the ceiling is 14*14 = 196
The plaster covers 90 square feet.
196/90 = 2.18 pails.
Unfortunately, you have to buy 3 pails.
5. Draw a line from the end of the 14 foot line to the 20 foot line so that the two lines meet at right angles. You have a small trapezoid on the right.
Area of the trapezoid = (b1 + b2)*h/2
b1 = 12
b2 = 10
h = (20 - 14) = 6
Area = (12 + 10)*6/2 = 22*6/2 = 132/2 = 66 square inches.
Area of the rectangle on the left = L * W
L = 12
W = 14
Area = 12 * 14
Area = 168
Total Area = 168 + 66
Total Area = 234 square inches.
6.
Area = b*h
B = 10
h = 17
Area = 17 * 10
Area = 170 square cm

C and D are both false. If squares have the same area, they have the same perimeter. If squares have the same perimeter they have the same area.
So it's between A and B and only one of them is correct because they are opposite in given properties.
Rectangles need not have the perimeter to have he same area. Suppose you have a rectangle that is L = 5 and W = 4 The area is 20. The perimeter is 18.
Now let is suppose you have a rectangle that is L = 10 and w = 2 The area is 20 the Perimeter is 24.
