Can someone please help me out? I would really appreciate it. No links or fake answers please. Thanks for understanding. The area of a rectangle is 72 sq. ft. If the length is twice the width, what is the measure of the length of the rectangle?
A. 6 ft
B. 12 ft
C. 18 ft
D. 24 ft

B

Step-by-step explanation:

The area of a rectangle is given by:

Where w is the width and l is the length.

We are given that the length is twice the width. In other words:

We also know that the area is 72 square feet.

Substitute:

Solve for w:

Divide both sides by two:

And take principal square root of both sides:

So, the width is six feet.

And sine the length is twice the width, the length is 12 feet.

Our answer is B.

add 6% to the value she got from selling the house.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
