Question

The length of a rectangle is 3 inches less than twice the width. If the perimeter of the rectangle is 18 inches, find the width of the rectangle.
__Inches

Answer 1

Let:
Breadth of rectangle=b
According to the question, Length is 3 inches less than twice the width
Therefore, Length of the rectangle=2b-3
Perimeter of a rectangle=2(Length)+2(Breadth)=2(Length+Breadth)
But given perimeter is 18
Hence,
2[(2b-3)+b]=18
Solving this equation we get,
Length=5 inches and Breadth=4 inches
