The length and width of the fence should be made 76.25 feet and 23.75 feet respectively. Also, the expression for the length is L = 3W + 5 and the perimeter is P = 2(4W + 5).

<h3>How to determine the fence's dimension?</h3>

Mathematically, the perimeter of a rectangle can be calculated by using this formula;

P = 2(L + W)

<u>Where:</u>

  • P is the perimeter of a rectangle.
  • L is the length of a rectangle.
  • W is the width of a rectangle.

Since the length of this fence is 5 more than 3 times the width, we have:

L = 3W + 5

Substituting the given parameters into the formula, we have;

200 = 2(3W + 5 + W)

200 = 2(4W + 5)

200 = 8W + 10

8W = 190

W = 190/8

W = 23.75 feet.

For the length, we have:

L = 3W + 5

L = 3(23.75) + 5

L = 76.25 feet.

WHAT IS THE ANSWER FOR 12 1/3 + 8 3/4 +17 2/8 +23 2/3=
gulaghasi [49]
12  \dfrac{1}{3}  + 8  \dfrac{3}{4}  +17  \dfrac{2}{8}  +23  \dfrac{2}{3}

Simplify
= 12  \dfrac{1}{3}  + 8  \dfrac{3}{4}  +17  \dfrac{1}{4}  +23  \dfrac{2}{3}

Change the denominators to be the same
= 12  \dfrac{1 \times 4}{3 \times 4}  + 8  \dfrac{3 \times 3}{4 \times 3}  +17  \dfrac{1 \times 3 }{4 \times 3}  +23  \dfrac{2 \times 4}{3 \times 4}

= 12  \dfrac{4}{12}  + 8  \dfrac{9}{12}  +17  \dfrac{3 }{12}  +23  \dfrac{8}{12}

Combine into single fraction
= 60  \dfrac{24}{12}

= 62
