Question

A rectangular quilt is 5 feet wide and 7 feet long. How many feet of lace are needed to cover the edges of the quilt?

Answer 1

P = 2L + 2W
L = 7
W = 5
P= ???
P = 2*7 + 2*5
P = 14 + 10
P = 24 feet of lace.

Answer 2

The rectangular quilt has length 7 feet and width as 5 feet.

In order to find the perimeter, we have this formula:

$P = 2(l+w)$

Plugging these values in the formula:

$P = 2(7+5)$

Perimeter = 24 feet.

So 24 feet of lace are needed to cover the edges of the quilt.
