Rosyth Sch 2006 PSLE Math Prelim Q31

Tammy has 24 fifty-cent coins. If she were to arrange all the coins to form the outline of a rhombus, what would be the total value of the coins on one side of the rhombus?


24 coins - 4 corners ----- 20 coins
20 coins divided by 4 sides ----- 5 coins per side

5 coins per side + 2 coins at the two corners ----- 7 coins
7 coins x $0.50 ----- $3.50

Answer: The value of the coins on one side will be $3.50
