Perimeter and Area — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A flower bed is 6 m long and 3 m wide. Its area is 18 square m.
Area = length x width, so 6 x 3 = 18 square m.
2. A square dance floor has 8 ft sides. Its perimeter is 32 ft.
A square has 4 equal sides, so 4 x 8 = 32 ft.
3. A craft paper is 10 inches long and 7 inches wide. Its perimeter is 34 inches.
Add all four sides: 10 + 7 + 10 + 7 = 34 inches.
4. A bedroom is 11 feet long and 9 feet wide. Its area is 99 square feet.
Area = length x width, so 11 x 9 = 99 square feet.
5. A square kitchen tile is 4 cm on each side. Its area is 16 square cm.
A square's area is side x side, so 4 x 4 = 16 square cm.
6. A welcome mat is 5 feet long and 2 feet wide. Its perimeter is 14 feet.
Add all four sides: 5 + 2 + 5 + 2 = 14 feet.
7. A rectangular garden is 13 m long and 5 m wide. Its area is 65 square m.
Area = length x width, so 13 x 5 = 65 square m.
8. A square coaster is 7 cm on each side. Its perimeter is 28 cm.
A square has 4 equal sides, so 4 x 7 = 28 cm.
9. A photo is 8 inches long and 6 inches wide. Its area is 48 square inches.
Area = length x width, so 8 x 6 = 48 square inches.
