Question

A farmer wants to plant three rectangular fields so that the widths are the same. The areas of the fields, in square yards, are given by the expressions 21x^2y, 35xy^2, and 14xy. What is the greatest possible width of the fields if x = 2 and y = 4?

Answer 1

21(2²)(4) = 21(4)(4) = 336

35(2)(4²) = 70(16) = 1,120

14(2)(4) = 14(8) = 112

GCF = 112
