<h3><u>Given</u>:-</h3>
Length(l) of the rectangle is three times it's width(w) = 3w.
Width(w) of the rectangle = w.
Perimeter of the rectangle = 64in.
<h3><u>To Find</u>:-</h3>
Length and width of the rectangle.
<h3><u>Solution</u>:-</h3>
Perimeter of rectangle = putting the value of perimeter, l and w from the above given)
64 =
64 =
64 =
=
=
Therefore, <u>width of the rectangle = 8in.</u>
And <u>Length</u> = 3(8)in. = <u>24in</u>.
To check whether the answer is correct or not, we can put the value of length and width in the formula =
Since, the perimeter of the rectangle is same as given in the question, therefore the value of length and width are correct.
