Front

What is Perimeter?

Back

The perimeter is the total distance around the outside of a shape.

Front

How do you calculate the perimeter of a rectangle?

Back

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

Front

What is Area?

Back

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

Front

How do you calculate the area of a rectangle?

Back

Multiply the length by the width: Area = length × width.

Front

What is the formula for the area of a square?

Back

Area = side × side or Area = side².

Front

If a square has a side length of 4 cm, what is its area?

Back

Area = 4 cm × 4 cm = 16 cm².

Front

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

Back

Perimeter = 4 × side = 4 × 5 cm = 20 cm.

Front

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

Back

Use the formula P = 2(length + width) and solve for the missing side.

Front

What is the perimeter of a shape with sides measuring 10 cm, 12 cm, 8 cm, and 6 cm?

Back

Perimeter = 10 + 12 + 8 + 6 = 36 cm.

Front

If a sheep pen has a width of 63 inches and a perimeter of 158 feet, how do you find the length?

Back

Convert perimeter to inches (158 ft = 1896 in), then use P = 2(length + width) to find length.
