This Grade 5 sheet provides additional rectangle perimeter and area practice. Students apply formulas to rectangles and squares with whole-number dimensions, decide between linear and square units, and explain measurement choices. Sentence correction targets common errors like missing square units, fill-in problems vary the unknown side, and short-answer prompts connect perimeter to trim and area to carpet so students see practical reasons for each formula in everyday settings.

Perimeter, Area, and Surface Area
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Area of a 12 cm by 5 cm rectangle is 34 cm.
Rewrite: Area of a 12 cm by 5 cm rectangle is 60 sq cm.
2. Fix the sentence:
A 10 m by 10 m square has perimeter 100 m.
Rewrite: A 10 m by 10 m square has perimeter 40 m.
3. Fix the sentence:
A rectangle 7 ft by 2 ft has area 14 ft.
Rewrite: A rectangle 7 ft by 2 ft has area 14 sq ft.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A 15 cm by 6 cm rectangle has area 90 sq cm.
2. A 12 m by 8 m rectangle has perimeter 40 m.
3. A square with side 9 ft has area 81 sq ft.
4. A rectangle 11 in by 4 in has perimeter 30 in.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why must area be measured in square units like sq ft?
Area covers a two-dimensional surface, so we count square units that fit inside. Multiplying two lengths in feet produces square feet, which describes how much surface is covered.
2. A rug is 9 ft by 6 ft. How much trim and how much carpet do you need?
Trim equals perimeter: 2(9+6) = 30 ft. Carpet equals area: 9 x 6 = 54 sq ft. So you buy 30 feet of trim and 54 square feet of carpet.
