Example Question #1 : How To Find The Length Of The Side Of A Pentagon
A pentagon with a perimeter of one mile has three congruent sides. The second-longest side is 250 feet longer than any one of those three congruent sides, and the longest side is 500 feet longer than the second-longest side.
Which is the greater quantity?
(a) The length of the longest side of the pentagon
(b) Twice the length of one of the three shortest sides of the pentagon
It is impossible to tell from the information given.
(a) is greater.
(b) is greater.
(a) and (b) are equal.
(b) is greater.
If each of the five congruent sides has measure , then the other two sides have measures and . Add the sides to get the perimeter, which is equal to feet, the solve for :
feet
Now we can compare (a) and (b).
(a) The longest side has measure feet.
(b) The three shortest sides each have length 856 feet; twice this is feet.
(b) is greater.
Example Question #122 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
A regular pentagon has perimeter one yard. Which is the greater quantity?
(A) The length of one side
(B) 7 inches
(A) and (B) are equal
It is impossible to determine which is greater from the information given
(B) is greater
(A) is greater
(A) is greater
One yard is equal to 36 inches. A regular pentagon has five sides of equal length, so one side of the pentagon has length
inches.
Since , (A) is greater.
