Problema Solution
The length of a rectangle is 11ft less than three times the width, and the area of the rectangle is 42 ft2. find the dimensions of the rectangle
Answer provided by our tutors
let
w = the width of the rectangle, w>0
3w - 11 = the length of the rectangle (11 ft less than three times the width)
A = 42 ft^2 the area of the rectangle
A = length*width
(3w - 11)*w = 42
by solving we find:
w = 6 ft
click here to see the step by step solution of the equation:
3*6 - 11 = 18 - 11 = 7 ft
the dimensions of the rectangle are: the width is 6 ft and the length is 7 ft.
