Answer:
Width 6.85
Length 13.7
Explanation:
There is no question, so I guess they are asking what is the length and width of the rectangle.
Perimeter is the measurement around the rectangle.
We have two widths and 2 lengths. The lengths are equal to 2 widths
Perimeter = w + w + 2w + 2w
Perimeter is 3 x 13.7 = 41.1
41.1 = w + w + 2w + 2w Combine like terms
41.1 = 6w Divide both sides by 6
6.85 = w
the width is 6.85 and the length is 2(6.85) = 13.7
