You can put this solution on YOUR website! Hi, there.
You have a multi-step problem, so let's go through this step by step.
[I]
First, ask, "What question am I trying to answer?"
.
At the very end of the word problem, we are asked, "How many feet should Nashaly tell the company?" Notice that the problem asks how many FEET. That's important.
.
[II]
Now we need to find the distance around the edge of one of the windows. In official mathematical language, this is called the PERIMETER. Each window is 47 inches tall and 30 inches wide. To find the perimeter we add two heights and two widths,
The perimeter of one window is 154 inches. If you are not sure how I got this, try drawing a picture of the window. Then label it with the heights and widths.
.
[III]
We want the perimeter for six windows, so we multiply 154 inches by 6.
The perimeter of all six windows is 924 inches.
.
[IV]
Remember that we want to know "How many FEET should Nashaly tell the company?" Our final step will be to convert 924 inches into feet.
.
We will use the conversion fact that 12 inches is equivalent to 1 foot. We have 924 inches and we want to break them up into groups of 12 inches each, so we divide 924 by 12.
Nashaly should tell the company that there are 77 feet.
.
Hope this helps! Please feel free to email me, if you are confused about this solution.
Best,
