A standard Stop sign has 8 sides, each of which measures 10 inches in length. A special Yield sign built to be seen from a great distance is an equilateral triangle with sides of 26 inches each and three reflective circles attached to the front, each with a radius of 1.5 inches.


Quantity A
Quantity B
the perimeter of the Stop sign
the perimeter of the Yield sign



A. Quantity A is greater
B. Quantity B is greater
C. The two quantities are equal

Perimeter of yield will be perimeter of triangle (26*3=78 cm)+ perimeter of the three circles (3*2pir=6pir=9pi)=78+28.26=106.26
What will be perimeter of stop sign?

Won't it be 10*4*8=320 cm?

If it's an octagon, then perimeter is simply 8*10=80. The tricky part should be Quantity B, but I would argue it is D.

Well it can be an octagon too.

Quote:
The perimeter of a polygon is found by adding up the lengths of all its sides, or multiplying the length of one side by the number of sides if all sides are of equal length. An 8-sided Stop sign with sides of 10″ length has a perimeter of P = ns = 8(10″) = 80″. An equilateral triangle has three sides of equal length, so this special Yield sign has a perimeter of P = ns = 3(26″) = 78″. Information regarding the reflectors attached the front of the sign is irrelevant and should be ignored, as perimeter is the measure of a shape’s exterior edges. 80″ > 78″, so the Stop sign has a greater perimeter and the answer is a.

What a way to trick or waste our time by this line and three reflective circles attached to the front, each with a radius of 1.5 inches which is of no use to solve this question
