Question

Wendy wants to put a wallpaper border around her bedroom. The room has two walls that each measure 10 feet 5 inches and two walls that each measure 6 feet 1 inch.

How many yards of wallpaper border must Wendy buy?

11 yards
33 yards
5.5 yards
16 yards

Answer 1

Perimeter = 2(10 ft 5 in) + 2(6 ft 1 in) = 2(125 in) + 2(73 in) = 250 in + 146 in = 396 in = 33 ft = 11 yd.

Answer: 11 yards.
