Missing sides in Area and Perimeter

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width)

Front

If a rectangle has a perimeter of 34 cm and a width of 6 cm, what is the length?

Back

Length = (Perimeter/2) - Width = (34/2) - 6 = 11 cm.

Front

What is the perimeter of a square with a side length of 3 inches?

Back

Perimeter = 4 × side length = 4 × 3 = 12 inches.

Front

If the perimeter of a rectangle is 28 units and one side is 7 units, what is the other side?

Back

Other side = (Perimeter/2) - one side = (28/2) - 7 = 7 units.

Front

What is the area of a rectangle with a length of 5 cm and a width of 4 cm?

Back

Area = length × width = 5 cm × 4 cm = 20 cm².

Front

How do you find the missing side of a rectangle if you know the perimeter?

Back

Use the formula: Missing side = (Perimeter/2) - known side.

Front

What is the length of one side of a square if the total perimeter is 20 cm?

Back

Length of one side = Perimeter/4 = 20 cm/4 = 5 cm.

Front

If a rectangle has a width of 4 meters and a perimeter of 34 meters, what is the length?

Back

Length = (Perimeter/2) - Width = (34/2) - 4 = 13 meters.

Front

What is the definition of perimeter?

Back

Perimeter is the total distance around a two-dimensional shape.

Front

If a square has a perimeter of 16 cm, what is the length of one side?

Back

Length of one side = Perimeter/4 = 16 cm/4 = 4 cm.
