The rectangles on a quilt are 4 in. wide and 5 in. long. The perimeter of each rectangle is made by a pattern of green thread. If there are 40 rectangles in the quilt, how much green thread is needed?
Answered by Ms. Sue
Are the rectangles all joining each other? On how many sides? Or are all rectangles separate?

It doesn't say.

Ok. Let's assume that you need the green thread around each of the rectangles.

P = 2L + 2W
P = 2(4) + 2(5)
P = 18 cm for each rectangle

18 * 40 = ?
