Question

Find the perimeter of a rectangular yard that measures 33 1/2 feet in width and 12 5/6 in height.

Answer 1

Perimeter is the distance around a shape. The formula is:

$2l+2w$

Fill in the numbers into the equation:

$(33 \frac{1}{2} \times 2 ) + (12 \frac{5}{6} \times 2 )$

$33 \frac{1}{2} = 33.5 \\ 33.5 \times 2 = 67$

$12 \frac{5}{6} \times 2 = 12 \times 6 + 5 \\ 12 \times 6 + 5 = \frac{77}{6} \times 2 =\frac{154}{6}= 25 \frac{4}{6}$

Now add both of them:

$25 \frac{4}{6} + 67 = 92 \frac{4}{6} \rightarrow 92 \frac{2}{3}$

The perimeter is $92 \frac{2}{3}$
