Perimeter

Front

What is the formula to find the perimeter of a shape with equal sides?

Back

P = side + side + side + side (or P = 4 × side for squares)

Front

What does perimeter mean?

Back

The distance around the shape.

Front

If one side of a square is 5cm, what is the perimeter?

Back

P = 5 + 5 + 5 + 5 = 20cm.

Front

What is the perimeter of a rectangle with length 4cm and width 3cm?

Back

P = 2 × (length + width) = 2 × (4 + 3) = 14cm.

Front

What is the perimeter of a triangle with sides 3cm, 4cm, and 5cm?

Back

P = 3 + 4 + 5 = 12cm.

Front

If the perimeter of a rectangle is 20cm and the length is 6cm, what is the width?

Back

Width = (Perimeter/2) - Length = (20/2) - 6 = 4cm.

Front

What is the perimeter of a shape with sides measuring 2cm, 3cm, and 5cm?

Back

P = 2 + 3 + 5 = 10cm.

Front

If a square has a perimeter of 24cm, what is the length of one side?

Back

Length of one side = Perimeter/4 = 24/4 = 6cm.

Front

What is the perimeter of a shape with sides measuring 7cm, 7cm, and 3cm?

Back

P = 7 + 7 + 3 = 17cm.

Front

What is the perimeter of a rectangle with length 10cm and width 2cm?

Back

P = 2 × (10 + 2) = 24cm.
