The area of a rectangular garden is 54 square feet. if the width of the garden is 1.2 feet, what is its length, in feet?

a.4.5
b.16
c.45
d.64.8

C) 45
The formula for the area of a rectangle is A = length * width, so to solve for the length, I must divide the area by the width.

A = 54, w = 1.2
54/1.2 = 45

The length is 45 feet. You can check this by multiplying 1.2 by 45, and if you get 54 (which you do), you have the correct length.

Hello there!

To solve for your problem, we need to understand the problem and how to handle it properly. Let's take a look into our question.

"The area of a rectangular garden is 54 square feet. If the width of the garden is 1.2 feet, what is its length in feet?"

We need to address what the area for a rectangle is.
The area for a rectangle is Length x Width. Let's state this in a more simple term.
A = L * W
We have our area, 54, and our width, 1.2.
Let's plug these numbers in to their proper spots in the formula.

54 = L * 1.2 --> 54 = 1.2L
Now, our goal is to isolate L (or solve in this matter - both are correct ways). To isolate and solve for L, we need to get rid of the 1.2 that is being multiplied by L. In order to solve for L, we need to divide 1.2 on both sides.

Divide both sides by 1.2;
54 / 1.2 = 45
1.2L / 1.2 = L

We are now left with the following solution:
L = 45.

Your answer is C.) 45.

I  hope this helps!
