Problema Solution
A picture framemhas a total perimeter of 3 feet. The width of the frame is 0.65 times its length. Find the dimensions of the frame. (Round your answers to two decimal places.)
Answer provided by our tutors
let
l = the length of the frame
w = the width of the frame
P = 3 ft the perimeter and P = 2(l + w) thus
2(l + w) = 3 divide both sides by 2
l + w = 3/2
the width of the frame is 0.65 times its length
w = 0.65l
by solving the system of equations
l + w = 3/2
w = 0.65l
we find
l = 0.91 ft
w = 0.59 ft
