Question

A picture is 6 inches longer than it is wide and has an area of 167

square inches. What are the dimensions (in inches) of the picture.
Round your answers to two decimal places.

Answer 1

A) L = W + 6

B) L * W = 167 OR L = 167 / W

Substituting B) into A)

167 / W = W + 6

Multiplying both sides by "W" we get

167 = W^2 + 6W

W^2 + 6W -167

Solving by the quadratic formula

Width = 10.266

Length = 16.266
