Problema Solution

The area of a rectangle is 45ft^2 and the length of the rectangle is 1ft more than twice the width. Find the dimensions of the rectangle.

Answer provided by our tutors

let


l = the length of the rectangle

w = the width of the rectangle


the length of the rectangle is 1ft more than twice the width


l = w + 1


the area of a rectangle is 45ft^2


w*l = 45


lets plug l = w + 1 in the above equation


w(w + 1) = 45


by solving the quadratic equation we find


w = 6.23 ft


l = 7.23 ft
