The length of rectangular garden is 7 feet longer than the width. If the area of the garden is 18 square feet, find the length and width of the garden. The length is ft The width is ft

The length is 9 ft and the width is 2 ft

Step-by-step explanation:

Rectangle:

Has two dimensions: Length(l) and width(w)

The area is: A = l*w

In this question:

A = 18.

The length of rectangular garden is 7 feet longer than the width.

This means that l = 7 + w.

So

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

.

This polynomial has roots such that , given by the following formulas:

In this question:

So

Then

A dimension cannot be negative, so the width is 2 feet, that is, w = 2.

l = 7 + w = 7 + 2 = 9 ft

The length is 9 ft and the width is 2 ft
