Question

two sides of a rectangular fence are 5 5/ 8 feet long. the other two sides are 6 1/4 feet long. what is the perimeter

Answer 1

Because a rectangle has four sides and the opposite sides are the same length, you can simply multiply each of the given sides (5 5/8 feet and 6 1/4 feet) by 2, and then add them together. 
5 5/8 × 2 = 11 1/4.
6 1/4 × 2 = 12 1/2
11 1/4 + 12 1/2 = 23 3/4 or 23.75

Therefore, the perimeter of the rectangle is 23.75 feet.

Answer 2

By definition, the perimeter of a rectangle is given by:

$P = 2w + 2l$

Where,

w: width of the rectangle

l: length of the rectangle

Substituting values in the given equation we have:

$P = 2 (5 \frac{5}{8}) + 2 (6 \frac{1}{4})\\P = 23.75 feet$

Rewriting the expression we have:

$P = 23 \frac{3}{4} feet$

Answer:

the perimeter is:

$P = 23\frac{3}{4} feet$
