AREA AND PERIMETER 3RD GRADE

Front

What is the perimeter of a rectangle?

Back

The perimeter is the total distance around the rectangle, calculated by adding the lengths of all four sides.

Front

How do you find the area of a rectangle?

Back

Multiply the length by the width (Area = Length x Width).

Front

What is the formula for finding the perimeter of a rectangle?

Back

Perimeter = 2 x (Length + Width).

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Back

50 square centimeters (10 cm x 5 cm = 50 cm²).

Front

If a rectangle has a length of 8 m and a width of 3 m, what is its perimeter?

Back

22 meters (Perimeter = 2 x (8 m + 3 m) = 22 m).

Front

What is the area of a square with a side length of 4 ft?

Back

16 square feet (Area = Side x Side = 4 ft x 4 ft = 16 ft²).

Front

What is the perimeter of a square with a side length of 5 in?

Back

20 inches (Perimeter = 4 x Side = 4 x 5 in = 20 in).

Front

What is the area of a rectangle that is 6 ft long and 2 ft wide?

Back

12 square feet (Area = Length x Width = 6 ft x 2 ft = 12 ft²).

Front

If a rectangle has a perimeter of 30 cm and one side is 10 cm, what is the length of the other side?

Back

5 cm (Perimeter = 2 x (Length + Width) => 30 cm = 2 x (10 cm + Width) => Width = 5 cm).

Front

What is the area of a wall that is 10 ft high and 8 ft wide?

Back

80 square feet (Area = Height x Width = 10 ft x 8 ft = 80 ft²).
