Given Information
------------------------------------------------------------------
Square Area = 156.25m²
------------------------------------------------------------------
Formula
------------------------------------------------------------------
Area = Length x Length
------------------------------------------------------------------
Find Length
------------------------------------------------------------------
156.25 = Length x Length
156.25 = Length²
Length² = 156.25
Length = √156.25
Length = 12.5
------------------------------------------------------------------
Formula
------------------------------------------------------------------
a² + b² = c²
------------------------------------------------------------------
Find Diagonal
------------------------------------------------------------------
12.5² + 12.5² = c²
c² = 156.25 + 156.25
c² = 312.5
c = √312.5
c = 17.68m (nearest hundredth)
------------------------------------------------------------------
Answer: The diagonal length is 17.68m
------------------------------------------------------------------
Answer: 41/10 or 4.1 or 4 1/10
explanation: multiple each fraction by the number on the bottom and simplify.
You do 49.50 times 4% equals $1.98. You than add $49.50 plus $1.98 that equals to $51.48 the total you paid for the shoes
