Area and Perimeter Missing sides

Front

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

Back

Perimeter = 2 × (Length + Width)

Front

If a rectangle has a perimeter of 48 meters and a width of 10 meters, how do you find the length?

Back

Use the formula: Length = (Perimeter/2) - Width. So, Length = (48/2) - 10 = 14 meters.

Front

What is the formula for calculating the area of a rectangle?

Back

Area = Length × Width

Front

If the area of a rectangle is 48 square feet and the width is 6 feet, how do you find the length?

Back

Use the formula: Length = Area / Width. So, Length = 48 / 6 = 8 feet.

Front

What does 'area' represent in a shape?

Back

Area represents the amount of space inside a shape, measured in square units.

Front

What does 'perimeter' represent in a shape?

Back

Perimeter represents the total distance around the outside of a shape.

Front

If the area of a rectangle is 2,695 square units, what does this tell you?

Back

It tells you the total space contained within the rectangle.

Front

How do you find the width of a rectangle if you know the perimeter and the length?

Back

Use the formula: Width = (Perimeter/2) - Length.

Front

What is the perimeter of a rectangle with a length of 6 feet and a width of 8 feet?

Back

Perimeter = 2 × (6 + 8) = 28 feet.

Front

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

Back

Area = 10 × 5 = 50 square meters.
