AREA AND PERIMETER 3RD GRADE

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

• 20 meters

• 22 meters

• 24 meters

• 18 meters

How do you find the area of a rectangle?

• Add the length and the width (Area = Length + Width)

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

• Subtract the width from the length (Area = Length - Width)

• Divide the length by the width (Area = Length / Width)

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

• 2 cm

• 5 cm

What is the perimeter of a rectangle?

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

• The perimeter is the area of the rectangle divided by the length.

• The perimeter is the sum of the lengths of the two longer sides only.

• The perimeter is the distance from one corner of the rectangle to the opposite corner.

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

• 30 square centimeters (10 cm x 3 cm = 30 cm²)

• 40 square centimeters (8 cm x 5 cm = 40 cm²)

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

• 60 square centimeters (12 cm x 5 cm = 60 cm²)
