The area of a rectangle is 2 square feet. the perimeter of the rectangle is 9 ft. find the length, l , and width, w , of the rectangle. what is l squared plus w squared ?

To solve this question:

Doing this, we get that:

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:

Rectangle:

A rectangle has two dimensions, length l and width w.

It's area is given by:

It's perimeter is given by:

The area of a rectangle is 2 square feet.

This means that , and thus:

The perimeter of the rectangle is 9 ft.

This means that:

Since

Applying cross multiplication:

Solving the quadratic equation, we find the value of the dimensions.

It is a quadratic equation with . So

Thus, a possible answer is given by:

what is the answer?

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
