How much fencing will be needed to enclose a rectangular city park that is 1/12 mile long and 3/8 mile wide?

Answer 1

A rectangle has four sides, two pairs of the same length. The problem is asking for total fencing, or the perimeter.

2 * l + 2 * w = p

l is given as 1/12 mi, and w is given as 3/8 mi.

So plug that in and you get:

2/12 + 6/8 (mi) = p (mi)

Reduce the fractions:

1/6 + 3/4 (mi) = p (mi)

Do your favorite method of writing the fractions with the same denominator:

4/24 + 18/24 (mi) = p (mi)

22/24 (mi) = p (mi)

11/12 (mi) = p (mi) or 0.927 mi.
