Question

The length of a rectangle is 5m greater than its width and its area is 6m2. Find its dimensions.

[Hint: draw and label a picture]

Answer 1

Width = 1 m and length = 6 m

Explanation:

Let b is the width of the rectangle.

Length = 5+b

The area of the rectangle, A = 6 m²

We need to find the dimensions of the rectangle. We know that, the area of a rectangle is given by :

A = lb

`6=(5+b)b\\\\6=5b+b^2\\\\b=-6, b=1`

Width of the rectangle = 1 m

Length of the rectangle = 5+b = 6 m

Hence, this is the required solution.
