Answer:
As you probably know the perimeter of a rectangle is given by the formula 2l + 2w where the length and width are represented by the letters l and w .
In our case,
l = w + 5 ( since the problem states that the length is 5 more than the width)
70 = 2 (w+5) + 2w
70 = 2w + 10 + 2w
4w = 60
w = 15
l = 20
Our length is going to be 20 ft and our width 15 ft.
Explanation:
The perimeter is the sum of the two lengths and the two widths.
So if we let L = the length and W = the width, 2L + 2W = 70
If the length is 5 feet more than the width, then L = W + 5
Substitute W + 5 for L in the first equation--> 2(W + 5) + 2W = 70
2W + 10 + 2W = 70
4W + 10 = 70
4W = 60
W = 15
So L = 20
Plug these numbers back in to the question to make sure that they work.
Have fun.
Circle of fifths would be your answer
You arent done with the question!!! There fore people cant answer it
