Front

How do you find the perimeter of a rectangle?

Back

Add the lengths of all four sides or use the formula: Perimeter = 2(length + width).

Front

What is the perimeter of a square with each side measuring 5cm?

Back

20cm (because 5cm + 5cm + 5cm + 5cm = 20cm).

Front

If a triangle has sides measuring 3cm, 4cm, and 5cm, what is its perimeter?

Back

12cm (3cm + 4cm + 5cm = 12cm).

Front

What is the perimeter of a shape with sides measuring 8cm, 6cm, 8cm, and 6cm?

Back

28cm (8cm + 6cm + 8cm + 6cm = 28cm).

Front

If the perimeter of a square is 36cm, what is the length of one side?

Back

9cm (because 36cm ÷ 4 = 9cm).

Front

What is the perimeter of a rectangle with a length of 10cm and a width of 5cm?

Back

30cm (Perimeter = 2(10cm + 5cm) = 30cm).

Front

If a shape has a perimeter of 24cm and two sides are 6cm each, what are the lengths of the other two sides?

Back

6cm each (because 24cm - 6cm - 6cm = 12cm, and 12cm ÷ 2 = 6cm).

Front

What is the perimeter of a shape with sides measuring 2cm, 3cm, and 4cm?

Back

9cm (2cm + 3cm + 4cm = 9cm).

Front

If a square has a perimeter of 40m, what is the length of each side?

Back

10m (because 40m ÷ 4 = 10m).
