Answer key · Set A
All the way round
110 3 + 2 + 3 + 2 = 10 inches.
216 A rectangle has two sides of 6 and two sides of 2. 6 + 2 + 6 + 2 = 16.
312 Add the three sides: 3 + 4 + 5 = 12.
420 A square has 4 equal sides. 5 + 5 + 5 + 5 = 20.
55 8 + 5 + 8 = 21 so far. 26 - 21 = 5 inches.
616 The rectangle is 3 feet by 5 feet. 3 + 5 + 3 + 5 = 16.
726 9 + 4 + 9 + 4 = 26 feet.
822 Go round once: 6 + 2 + 3 + 3 + 3 + 5 = 22 meters.
9the one on the right The left one is 3 + 2 + 3 + 2 = 10 units round. The right one is 6 + 1 + 6 + 1 = 14.
10False That counts the area. The perimeter is the distance all the way round.
11True The rectangle is 2 by 5. 2 + 5 + 2 + 5 = 14.
125 + 3 + 5 + 3 Perimeter is all the way round, so add all four sides.
