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

what the question so we can you out

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
