Problema Solution
the length of a rectangle is 3 yd less that twice the width, and the area of the rectangle is 14 yd squared. find the dimensions of the rectangle.
Answer provided by our tutors
Let 'x' represent the width.
The length is: 2x - 3
The area A = 14 yd^2.
Also A = width*length that is:
x(2x - 3) = 14

........
x = 3.5 yd
We need to ignore the negative solution -2 since the width can not be negative.
2*3.5 - 3 = 7 - 3 = 4 yd
The width is 3.5 yd while the length is 4 yd.
