Domenico has forgotten 1 dimension of a
Perimeter = 46m
room. What is the missing dimension?
Three students each began to solve the problem.
Domenico wrote: P= Length + width + length + width
46 = 16 + width + 16 + width
Diane wrote P = (2 x Length) + (2 x Width)
46 = (2 x 16) + (2 x width)
Owen wrote: P = 2(length + width)
P = 2(16 + width)
Complete each students work to find the missing
dimension. Which method do you prefer? Explain why.
